Which ones? I have other hand cannons that I have loved. I love Thorn, yet I've still never played PvP with it.
I had a v1 Red Hand IX which was an incredible weapon. Word of Crota is kinda meh.
I have TLW - don't play with it much, for some reason the fanfire animation drives me crazy...but then again I don't have the Last Word perk unlocked
But Fatebringer - oh my, what a fantastic weapon.
I play on XBone, so I won't have the pleasure of Hawkmoon for a bit and I hear that gun is just amazing.
[b]Hawkmoon[/b] (3 lucky bullets with amazing DMG),
[b]Word of Crota[/b] (so fast to kill ppl in PvP, amazing balance between Impact and Rate of fire),
[b]TLW[/b] (hate it, good for ppl who can't aim and hope for random hits),
[b]Timur's Lash[/b] (so amazing DMG) with Crowd Control + Field Scout,
Grind mate. It is worth it. I spent 60 motes of light to get mine. It is not "perfect" but I am really happy with perks.
You can check it on my hunter. The best would be replacing spray and play with "precision shots shorten the reload time" but still really like it.
