What's your favorite Civ faction to play as, and least favorite Civ to play against?

Right now I'm playing as the England on 5 and I'm loving the Longbow men range. I only had 4 longbows and was able to thwart 7+ units of Babylonians, wave after wave. Plus I had the Great Wall so made it easier to rain in on them.

I'm also a bit behind on the tech so that additional Spy is becoming very useful.

I hate playing against the Huns because they always raze every city and Babylon in every game I play against always is hostile to me.
