Greeks.
I don't like war, so the Hoplite helps alot. It's basicly a pikeman 1/3/1, but needs no iron, cost 20 instead of 30, and is around at the very begining of the game. Also the commercial/science trait combo is the best for science research, which I love to do. If you are a builder not a fighter you should really give the Greeks a try.
On a sidenote when I want to go for a fast military win I got with Zulu.
