OK, that's good. Come to think of it, most UUs have a good way to use them
The carrack looks pretty lame; a bog standard caravel that can house another missionary/explorer.
The Navy SEAL - because marines are lame, and the SEAL is just an upgraded marine.
And I'm tempted to add the War Chariot! The immunity to first strikes would be gained thorugh Flanking anyway. Still, not the worst; the increase in strength ensures that.
Any of Dog soldiers/Jaguar Warriors and Ballista elephants as has already been mentioned.
I thought the native american UU in Civ 3 was better (mounted so needed horses but was quite reasonable iirc).
Doesn't the Impi get to keep the extra movement point when it upgrades? That right there is a good reason to build a lot of Impis.
I strongly dislike Dog Soldiers as well... a PRO leader shouldn't need them for defense and offensively they are quite often a liability rather than an asset.
Ballista Elephants and Panzer might be low-impact UUs but at least I won't rant about wishing to have the regular unit instead.
Fast Worker is IMO generally the best UU in the game. It saves numerous worker turns in every game. Some military UUs can be stronger in some certain situations (like Quechuas in Dual map) but none of them is useful in every game like the FW.

Also, yeah, fast workers never go obsolete in the sense that you can always build them but imo they do go obsolete in the sense that by around the mid to late renaissance your infrastructure is largely completed and you can comfortably pump out a ton of workers from high production cities and so having faster workers becomes completely irrelevant.
