I'm going with Greece. Being a Greek myself, naturally I chose this Civ to play with when I first started playing the game. And I must admit, in CiV, his UA is one of my favorites, especially because I like to build strong relationships with surrounding CS's. Additionally, the hoplite has proven to be a valuable UU to me over time (since Civ3) and one that I can usually count on well into the early Middle Ages.
The Americans come in at a close second.
