Immortal
Hm. I've never actually played the Maya but I assumed they got a fair number of them more than a standard civ.
Put simply, the Mayan UA is 6 free great people over the entire course of the game (each have to be different, so no 6 free GE's). Enter medieval era with theology to maximize its effect a little (hopefully). For the Swedes, depending on how you manage your diplomacy, you could get GP's twice as fast as other civs. To maximize Swedish UA, aim for cultural victory early in game and then for diplomatic victory and then choose either Order or Freedom ideology to get the 25% GP bonus.
Also, I might end my support for Sweden if people can criticize it for other reasons. I can name at least 2 that haven't really been mentioned.
