Except he didn't, he became the primal Phoenix from all the prayers around Eorzea, didn't he? He's using borrowed power.

Though if we're talking after they've achieved complete mastery over their job, it's undoubtedly Black Mage, using Shantotto as my reference here. The ability to travel dimensions and obliterate worlds with ease, I'm sorry but destroying a weak Ascian doesn't compare to that. But they're pretty boring in game to be honest.
