I've never even spared a second glance at the "sounds like this is a jorb for a wookiee," or some such. I honestly don't like using him at all. I really prefer characters that speak "basic". I get VERY tired of, what do they call it, shuriwook on Kashyyyk (which is the only place I really use him).
On my first playthrough, I used Mission. I've used her for most of them, I think. I've also used Jolee, though, and I'd have to say he's my favorite. I find his dialog hilarious, and he can easily wipe out all the resistance with his force powers, not to mention he's got classy underwear.
