Meaning that unless the encounter specifically emphasizes the AoE phase over the single target phase, it doesn't really matter that much.
That said, both Tectus and from what I hear Mythic Imperator both have this, so Incarnation is better for both those fights. Soul obviously better for Butcher and a wash for everything else. Bracken its hard to say, but given the short duration the spore shooters are up, I'd say Soul wins here if not on flamethrower duty, and Inc wins with flamethrower.
Again, that's my gear, so trinkets and/or set bonuses could possibly change this.
