Depends on the character... Mechromancer with close enough is negatively affected by the redundant fibber's thing because of the damage decrease.
Sal benefits from both guns harold is better for its accuracy imo
Siren is better with the Harold because of explosive element and increased projectile speed will cause the spread to happen later
Zero Harold because Accuracy buffs and pistol fire rate and mag size will deal massive damage
Axton (havent used)
Overall I'm crutch on accuracy so I'd say the Harold but the fibber i've heard not too many bad things --- PSN/GT: CapTionisT You know you suck as a sidekick, Im just letting you know so that the next time you think you're bad@$$..don't do it ~ Desert Punk
B0re shots with the Harold are unholy as well. Zer0 gains great benefits from direct precision and because of low bulk too, The DP is a far better choice. --- What is a man?! A miserable little pile of secrets!
