Theoretically? I'd argue that it ranks above the mortal schools of magic, but below the power of the Divines or other god-like beings. Could a mortal armed with the Thu'um have driven back the Daedric Princes  or the Tribunal? Absolutely not, though it might have been the fight of an age.

Could several Tongues have turned the war against the Aldmeri Dominion? Very likely. Even a single Dragonborn might have turned the tide. Tiber Septim was able to use the Thu'um to reshape the very face of Tamriel.

Much like the Dragons themselves, the Thu'um is a sort of immortal, semi-divine thing.
