Everyone has one, the gun maker that you absolutely can't stand for whatever reason. For me, it's Dahl. Worst guns in the game for me because of the burst fire when zoomed. I'm the kind of guy who likes either a one bullet at a time or fully automatic. However, I absolutely LOVE the Hornet pistol. Got one the other day and it's been my go-to gun for loaders.
I agree with you about Dahl weapons - not a big fan of the burst fire weapons, but the hornet is pretty amazing.
If I had to pick a second, I'm not a big fan of Torgue guns because of the slower moving bullets, but the DP Unkempt Harold is pretty game-breakingly awesome. It's my go-to gun for Second Winds, and just destroying mobs quickly.
The Pitchfork has made me like Dahl a little bit. The caustic e-tech SMG of theirs is sucky as hell, though. Half the time, the DoT from it is just 1. As soon as I find another caustic e-tech SMG, I'm switching to that.
