Emperor
Feudalism is a fine government for warring. You whip lots of units. The whipping keeps the size of your towns low, and the small towns give you lots of unit support so you can afford all those units. If Feud sat in the tech tree where Republic is now, I'd happily pick it for any military games. Trouble is, by the time Feud is available, you probably already had Republic for a while; even when you miss the slingshot, researching Republic is often a good idea, for tech-trading reasons.
