Advice needed: devotion setup for Druid

So I’m basically torn between two devotion setups more defensive one, I am currently using and more offensive one with Rhowan’s Crown. Here are the grimcalc builds:

I’m also not sure whether it’s better to use nerfed Empty Throne or an Owl, so some advice here would also be helpful. Any constructive criticism is obviously welcome.
