Republic rocks. Especially ARC troopers. The Red ARC sniper mod makes them even cooler. Second choice would be CIS, since their tanks are my favorite.
I'm one of the rare CIS players, but I only love their droid starfighter :) and SBD
Empire assault, or scout trooper, if I'm rebel I'm assault or vanguard.
Rebels. i like having two rockets coming out of my rocket launcher (and not having to wait ten minutes to reload like the Republic ARC troopers). the uniforms, especially that of the Soldier (with color changing camo outfits) and the Vanguard (love that Naval Trooper outfit), are the best of the game.
next would be the CIS. why? not really sure as i like the Empire's troops better (Dark Troopers are useful, but not lamely over-powered like Jet Troopers). Maybe it's because you get to kill Jet Troopers! (if you haven't already noticed, i like killing Jet Troopers).
What? the Galactic Empire is in third place! what an outrage... guys probably haven't voted enough
The CIS. Do you know how quick opponents die with the Tri-blast? Even when far away, this is the best weapon.
i like the sbd's wrist rocket especially on playstation with infinite ammo fly troppers fly
Republic jet trooper all the way
Republic - ARC Trooper, however I play using the weapons addon mod so the ARC Trooper gets a clone trooper rifle as secondary... nothing beats a rocket + assault rifle combo :) plus I am a fan of the ARC Troopers. *points* http://forums.filefront.com/showthread.php?t=187929 And for all you CIS people out there... I would play as the CIS almost excusively as Battledroids are my favorite... but they ruined the faction by replacing the assault battledroid with the Super Battle Droid. It's not that I thin the sbd sucks, I just LOVE the standard battledroids... and they ruined it for me when they replaced my battledroid buddies with the sbd.
go the clone trooper just charge in gun blazing droids fall before you...mwu hwa ha ha ha
