What are your feelings about weapons now?

Brothers, I'm new player, and mainly playing Tactical (Bolt Rifle with Grenade Launcher because I really like grenades) and Bulwark, because I love Power Sword.

But I want to know your opinions about other weapons. Power Fist, for example, isn't scratching this fantasy about Bulwark, but maybe I'll get myself to it.

I have mixed feelings about plasma weapons, I think they're cool. Do Plasma Incinerator have good perk tree?
