Depends on build. Imo bee/sandhawk is best if you go kunai... Which is my personal favorite for UVHM. Slag is practically a must in that mode. Death mark is incredibly helpful too. If you're going melee law+order is good (don't have to drop points into resurgence). If you have Scarlett DLC the rapier is highest +melee dmg% weapon in game. As far as going sniper tree, it's a lot of fun... But there's a certain point where it looses viability. Even if properly geared.
