Here is my list for the best uses for Great People. I would like to know other people's thoughts in order to better all of our games.
Great Generals: I keep the first one for sure, usually keep the second one too. After that, I sack them for short Golden Ages (not as long as other great people). Too many people just sack their GG's without thinking about the amazing bonus of 25% they give to 2 squares in all directions. I've heard that a whole bunch of citadels is very effective close together, but unless you are playing Chinese, I don't see how you will get more than 4 or 5 GG's.
Great Scientist: I always use these for a free tech unless I am insanely ahead. The Great Scientist seems to be the most unbalanced Great Person in the game. Instead of like in CivIV where you get a certain amount of beakers, in V you get a free tech, period. If you can rock out 3 of these guys and hold them until you seem to get into a stalemate with your opponents, you can just sack these guys out get a completely unfair advantage. If anything, either the other Great People (minus maybe the General) need to get Greater, or the GS needs to get less Great!
Great Artist: Golden Age. The 'culture bomb' (are you serious about that name BTW, we can make up names, not you the developer)... is a decent bonus and it can really disrupt a contested land battle, but to use it effectively (rather than just declaring war and eliminating the problematic city) is rather difficult.
Great Engineer: Until the late game, I always save these for their 'hurry production' ability which is a great way to steal important earlier wonders you forgot (or don't have time) to build.
Great Merchant: Golden Age. I'd say these guys are the weakest of all Great People in my opinion. A trade route to a city state to make them happy? I could just pay them or sack barbs to make them happy. And the gold you get is not game-changing by any means. Maybe I am missing something with these guys, but I haven;t come up with a good way to use them that beats a free Golden Age.
Great Profit: Just checking if you are reading.
One thing I have found out that seems to be for sure is that the tile upgrades (to me) seem to be a complete and utter waste of a Great Person. Sure, they add some nice stuff, but they remove all workability of the tile and if there is a rare resource, they remove those too. They either need to have better tile attributes or not remove the existing (in my opinion).
