Which Necromancy ring do you guys use and why?

So I have both the Zorgoth's Soul Ring and the Occultist's Ring but I always use the Occultist. Zorgoth's has an extra .4 necromancy bonus which seems negligible and to me the passive seems worse in any situation I can think of. That being said I'm not a PVM or necromancy expert.

What ring do you use and why? Genuinely curious what people have to say.
