Ok, I'm level 28 and I only have one more upgrade on Bad Juju left. With the String of Curses perk, it becomes quite an excellent weapon. Like I said- no game changer, but I prefer it that way. As long as you're good with precision damage (and since I started with hand cannons precision damage is my bread and butter) it can be a beast for taking out streams of lower-tiered enemies like Dregs, Thralls, or Acolytes. But if you're going up against a bigger enemy like a Gate Lord or such, you probably want to switch to something with a little more punch. I only got the Thorn two days ago, but from what I've seen it also isn't that bad. The recoil is pretty standard for a hand cannon in my opinion and it also deals good damage. My only complaint really is the reload speed as I said above- I haven't taken the Thorn into the Crucible for this specific reason. Of course it all comes down to opinion in the end. If you don't like them, that's fine.
