Nekro for 1st place for sure. If you time we'll, you could be un-stunable.
If it's only for pvp, I'll say Sam too for its passive heals and panic. Or Maridos for 3rd choice.

Maridos is good for pve with banish. Armor buff and stat will be helpful in pvp but no panic.
Singe is OK too but no panic. And Maridos is overall better than singe.
Toor is just broken.

Stat bonus is good but not deadly significant unless you are low level twink. Even on twink I like sam tho. Personally preference.
