This old chestnut has probably been around for a long time on the internet and the Warhammer fanboys seem to heavily favor their uyniverse while the Star Wars fans prefer theirs.
Full disclosure I like Star Wars a lot and know more about it than Warhammer 40k. However I am fully aware Star Wars has some issues, inconsistencies and out right stupidity in it and from what I have read one can claim the same thing about WH40k. The other problem is what time era do you pick from the two genres? Can the Imperium of Man defeat the Republic, the Empire, the New/Old Republic or the First Order? Whats tougher a Space Marine or a Jedi?
For the most part I will assume tat the Imperium of Man (IoM) is from the 41st millenium or 8th edition of the Warhammer universe vs the Star Wars Galactic Empire (GE) just after the Empire Strikes back. Further I will make the following assumptions.
1. This is a mano a mano showdown, that is the Galactic Empire doesn't have to worry about the Rebellion, the Imperium of Man doesn't have to worry about losing the empire to Chaos/Orks/Necrons etc.
2. That the IoM warp drive work in the Star Wars Galaxy and that the Star Wars hyperspace equivalent works in the Warhammer universe. One can make arguments that neither one would actually function in the other universe (this applies more to WH40k than SW, the warp may not exist in other galaxies in WH40k lore AFAIK). The timelines also do not match up (Galaxy far far away a long time ago). It is possible for example the SW galaxy got eaten by the Tyranids although both the Sol system and Star Wars galaxy are in the same multiverse separated by time and space.
3. I will ignore some of the more silly aspects of the Star Wars EU (and would prefer it if any Warhammer fans kinda do the same). This is because they declared a lot of the old EU non cannon and some of it was also silly and over the top even back in the day. I will reference the legends stuff where it doesn't contradict the new canon or where both continuities share certain concepts. For a while their they had super weapons of the month that the Heroes of Yavin invariably blew up (death star prototype, galaxy gun, sun crusher etc).
First things first. The IoM and the GE are similar in various ways. Both are galactic level empires and both have a million worlds+ (accounts vary). Both have super weapons, and both can bombard a planet and render it inhospitable. Both can blow up a planet although such weapons are a bit more common in the Warhammer 40k universe. Warhammer superweapons are a bit more common than in Star Wars, Star Wars ones are bigger in scale or effect (Death Stars, Starkiller Base, various ones in the old EU). Basically if either universe wants to ruin your ball in space they can do it. In Star Wars they can at least pull a Base Delta Zero planetary bombardment, in Warhammer they use exterminatus order both have similar results.
Ground Power
As stated previously on paper the empires are both similar in size ( a million planets, trillions of beings). The Warhammer universe is a bit more over the top in its presentation and they have more hive worlds and forge worlds than the Star Wars equivalents. Hive worlds are just planets with super sized populations. Coruscant would be a similar example in the SW universe. The Imperium of Man relies heavily on its numbers and while the Empire is big they do not seem to have the numbers the IoM has even in the old EU. Star Wars has no equivilent of SPace Marines, the Stormtroopers are probably comparable to the Imperial Guard and although the GE has an Imperial army they are never really heavily featured in the movies or EU. The Empire has walkers, the IoM has Titans.
The GE lacks a Jedi order and does not have enough dark side users to go around so Space Marines are a problem although I believe they could be killed by existing Star Wars tech. One on one Ithink a Jedi Knight or Sith could defeat one buit there are around a million space marines and the Jedi (which the Empire lacks) only number ion the 5-15k range usually in the Star Wars universe. Warhammer universe weapons can definitely deal with Stormtrooper armor, a Titan can probably destroy a walker, although walkers can probably deal with the smaller titans as well. Star Wars has a higher tech level than Warhammer but on the ground I think Warhammer wins.
Fleets.
Space it is hard to rate the Warhammer Universe ships here vs the ships of the Galactic Empire. I suspect it could be an absolute wash out either way depending on ones take of the respective ship classes. The Warhammer battleships are bigger than Star Destroyers, but smaller than a Super Star Destroyer (SSD). SSD are kind of rare thoughboth in the new cannon and the older EU.. The Empire has around 25 000 Star Destroyers (ISD I and II's) at its height plus lots of older models such as Victory Star Destroyers and support ships like Strike Cruisers, escort Carriers down to system patrol ships.I'm not sure how big the IoM navy is.
Both have sector fleets. The GE sector fleets tend to be larger than IoM fleets but the IoM cruisers are bigger than the GE Star Destroyers. Sector fleets also vary in size a lot in the GE as some sector fleest might consist of older clone wars vintage ships and perhaps even a single Victory Class for sectors in the outer Rim. Battleships are a big deal in the IoM, Star Destroyers the GE equivalent seem a bit more common. GOing byy the fluff it is inescapable that Warhammer ships are generally bigger (with exceptions like Death Stars and Super class Star Destroyers), the GE might have the numbers when it comes to capital ships and they built 25 000 Star Destroyers in the 18 years from Revenge of the Sith to A New Hope. Warhammer Battleships do seem to be slow and unwieldy however but both the IoM and GE ships are shielded as well. If anyone can put some numbers on how many sectors the IoM has we can probably figure out who has the bigger fleet. Can a Star Destroyer take on a WH40k Battleship, can a WH40k Battleship deal with a Super Star Destroyer? TIE fighters are fairly rubbish and I believe the WH40k tech can deal with them, hell; Earth in 2017 can probably deal with them in atmosphere.
Technology levels.
Technology in Star Wars proceeds at a slow place compared with RL. In the Warhammer 40k universe they are arguably regressing. This is one area where Star Wars undeniably has a massive lead. This is most notable with hyper drive vs warp speed. In the WH40k universe it seems to take 1-4 years to get anywhere with warp speed. In the Star Wars universe hyperspace is a lot quicker. Flying from Tatooine (outer rim) to Alderaan (Core world) is a 8 hour trip in a X1 hyperdrive (such as an X-WIng). In the Falcon (0.5 hyperdrive) that is a 4 hour trip or a 16 hour trip in a imperial capital ship such as a Star Destroyer. 16 hours to get from the edge of the galaxy to the core. That is on a hyperspace route however but even a slow trip from one side of the galay to the other is going to be a few weeks of couple of months sort of trip. Only a very bad back up hyper drive on a completely unknown route in a vintage ship would get you the travel times of a fast WH 40k trip. By vintage I mean something from the Old Republic era with a X16 back up hyperdrive which was bad 5000 years ago in the SW universe. Put simply the galactic standard hyperdrives can run rings around the WH40k faster than light IoM systems.
So how far behind are the IoM relative to the imperial standard? The Warhammer 40k ships do have a resemblance to some of the Golden Age of the Sith ships but their warp tech is going back to roughly the early days of Star Wars hyperdrive tech and its somewhere bnetween 5-25000 years behind the Empire. This is also obvious with the day to day technology used in the Star Wars universe. For example they have droids which have not been a thing since the Dark age of Technology. Lightsabers are plasma technology and Star Wars blasters, capital weapons etc are more similar to plasma weapons than lasers as they are fueled by gas to fire super heated beams. Star Wars also tends to have miniaturised technology as a blaster pack for example is not much bigger than a modern cell phone battery pack. If the IoM capiatal weapons are as primitive as there warp drives they are in big trouble vs the Empire (or Republic or even the Rebellion). Its possible that IoM weapons can not penetrate Star Wars shielding as older Star Wars ships (which are arguably superior to WH40k ships) would be useless if they engaged modern Imperial/Rebel designs.
The IoM still seems to use a lot of projectile weapons for example and in the old EU Star Wars had things like planetary shields which seem t have no equivalents in WH40k. Put simply the technology level in Star Wars exceeds the technology level from the Dark Age of technology which in turn exceeds that of the IoM era. Best case scenario is the IoM weapons are roughly equivalent to the GE versions (shields/ship weappns) and they are hopelessly behind on faster than light travel. I don't think you could make the argument they are more powerful and SW ships alsop have good reactor and shield designs comparative to the IoM.
So who wins? The Galactic Empire or the Imperium of Man. Ultimately I think it depends on how much the difference the levels of tech in Star Wars favor can make in the fields of battle. Having uber space marines doesn't really matter if the Galactic Empire can run rings around your forces and/or annihilate your capital ships. If you can't land your troops or can space supremacy your uber commandos won't matter. The two franchises are different takes on the sci fi aspect of them (grim dark vs space opera). Ultimately I don't think the Imperium of Man can actually win based on their warp drives if nothing else. Assuming they can even damage the imperial troops I think this is what more or less happens.
The Imperium of Man decides to invade the Star Wars Galaxy (or vice versa). They have some victories using large numbers of imperial guard units, space marines and a battleship can engage a Star Destroyer successfully. However they have very very slow faster than light capabilities and it takes them a long time to replace things like Space Marines. In theory they have near infinite numbers of troops to throw at the Empire. Their very slow warp drives however means they can't win that war quickly. So best case scenario the Imperium of Man can't conquer or counter attack an early imperial incursion quickly. A single warp jump might last as long as the entire rebel/empire civil war.
Now Star Wars did have a grim dark plot line where extra galactic invaders the Yuuzhan Vong invaded the galaxy. The overall plotline was terrible but they trashed the galaxy and captured Coruscant and politically the New Republic was weaker than the Empire. The war dragged out but the New Republic (and the Empire) are capable of something the IoM is not and that is innovation. They can design new weapon systems a lot faster/easier than the IoM and they can have things like War Droids. The Trade Federation designed war drioids to shut down Jedi, there is no reason why they can't design droids (heresy I know but war is not fair) to kill Space Marines and Star Wars has several droid designs arguably on par with Space Marines (Yuzhaan Vong Hunters YVH droids, Annihilator War Droids, Droideka II,SD-9 and 10).
Star Wars also has things close to mega structures in Space. The IoM does have Mars but Star Wars has several planets like that along with fully automated worlds of droids that can crank out more droids. The Trade Federation could crank out millions of battle droids and in a long drawn out war there is no reason why the Empire could not do the same thing. Since the war is going to last a long time even if the IoM wins initial battles any reasonable tech from the current canon (TIE Defenders through to First Order techs), will likely be invented. From the movies we also know that it is technically possible to crank out battle druids and clone troops as well. Even if the IoM captures SW tech they can't back wards engineer it or produce it anyway either due to it being heresy (droids/AI), or barely understanding what they do have let alone the superior Star Wars tech. They can get shield generators onto droids down to the size of Droidekas in the current cannon and even smaller in the old legends EU.
If one throws in some of the silly ideas from the old EU or even the current movies (Star Killer Base) the IoM also has a giant weak spot. I am assuming that the Imperium can use there warp drives but they are dependent Emperor and the golden throne to navigate warp space. Starkiller Base and the Galaxy Gun and Sun Crusher in the Star Wars legends EU can destroy planets and unlike the Death Star they can do it stealthily either being smaller or having hyperspace capable weapons of mass destruction. If you can kill the Emperor of Mankind/blow up Sol you more or less win the war. The IoM navy is stranded and the Space Marines can't deploy. Killing Palpatine doesn't have the same effect (especially if Vader is unredeemed/alive).
So who wins? I lean towards the Galactic Empire, the IoM might be able to win in older timelines where the tech difference is a lot less or the Republic is not as militarised as the Empire (but then the Jedi entire the equation). The Imperium has some big ships and lots of men but I think they are the 19th century equivalent of dervishes charging maxim machine guns or the Yamoto vs the USN dive bomber. They are literally around 25 000 years behind in faster than light tech and probably 5000 years behind in ship to ship weapons and do not even have basic things like targeting computers (Luke turned his off). Their weapons are big but IDK if they can penetrate ISD shields, or planetary shields. They do have things like hive and forge worlds to a greater extent than Star Wars but the SW universe doesn't need them as they very efficient automated manufacturing and things like orbital ship yards and factory worlds on the galactic scale.
