I previous thread..about how powerful the Dragonborns are in comparison to the Tribunal got me thinking as to How Powerful the Thu'um really is it comparable to the powers like Sword Singing and Wild Hunt.

I'd say it's more impressive than Mysticism (if only because of it's versatility, it's like an entire new form of magic rather than just a new school) but somewhat less impressive than Sword Singing (At least until we see atomic Thu'um). The Wild Hunt would depend on the luck of the draw since it can't be controlled in any practical way.
