The Last Dragonborn was a hero from a prophecy, sent by the gods to kill Alduin the World-Eater, whereas Miraak was just the first of several talented individuals. He was insanely powerful, yes, but stronger than the ancient Nord God of Destruction? I doubt it. Let me put it like this; Miraak was in a fight that lasted multiple days; the combatants were both so powerful that the a chunk of skyrim BROKE OFF; The best the Dragonborn could do is knock a giant off a cliff.

Also the 'Prophecy' wasn't written down until the Akaviri invaders came to Tamriel, that was much later than Miraak's time; had Miraak fought Alduin, he would have won and the prophecy would have never been created.
