Since I've killed dozens of reavers already, I won't go with the Outlaws. I'll probably go Cleric. I much prefer ranged attacks over melee and most of the Beserker stuff is close range. I haven't met the Clerics yet though with any of my 5 or 6 characters. Hopefully, I'll stop starting over soon.
I consider reavers a completely separate faction from the Outlaws, if you even want to call them a faction.
Personally, I think both the Outlaws and Clerics are mostly asshats.
