I've been doing Brayflox as WHM and SCH and its pretty equal (mana management for WHM, working with poison stacks for SCH). I've done Cutter's Cry only as SCH and Stone Vigil as well recently. I found myself often in difficulty when deadling with frequent AoE (Stone Vigil especially). Does anyone would have advice on this ?

In general, I found that SCH is better when you already know the fights.
