Chichen Itza, Colossus, Petra, Leaning Tower, Red Fort and the ideological wonders.
GE-rushing Leaning Tower, then rushing Globe Theater with the free GE is one of my favorite things to do.
Since I typically play culturally, I will use GA/M/W for Great Works until they can't make them anymore, then pop them for whatever they'll give me. And while Manufactories are nice, there are too many wonders I want during the game.
Also, for building wonders, you have to be aware of which wonders the AI will beeline - given my focus on other wonders, Chichen Itza is usually gone before I ever get to Civil Service, so if you want it, you have to go straight for it and have a GE ready. Whereas the Hanging Gardens you can usually get with no trouble. Big Ben also usually doesn't go until everyone's in the Modern era.
