In both cases, the perks of Bad Juju and Red Death are intended for facing more than one enemy either consecutively or simultaneously. It's a FULL heal you get from kills with Red Death. That far outweighs the auto-reload of Bad Juju because if I'm facing multiple opponents either consecutively or simultaneously, that full heal will actually help keep me alive long enough to engage the rest. Having a fully reloaded magazine doesn't help you much if you're dead. As for the reload benefit of Bad Juju, it's only taking me 2 shots to kill someone with Red Death (3 if my aim is off) which is the same for Bad Juju. So it's unlikely I'll have to reload before I run out of players to kill in PvP, and I've never been caught reloading my Red Death. On the other hand, Bad Juju won't even reload automatically if you don't get the kill shot. Finally, Bad Juju does not compete well against all the Thorn users. Even if you kill them first, which you'll usually do, the DoT from the Thorn will still kill you. Red Death is the only gun I've seen that can keep you alive after beating someone with a Thorn. Not even the SUROS could do that, at least not consistently.
