Play-any-spell shell: mana MoM Hierophant vs Foulborn Ghostwrithe Rathpith Lifestacker Inquisitor, which is better?

I'm planning to play 1 build only this league that's selfcast. Anyone has experience playing these 2 can share any difference between them, for mapping and bossing? These 2 build looks very similar defensively: large EHP pool with high recovery, coupled with block, unless I miss something.
