*Wrong forum. Moving.
As for the thread, Vegito should win, honestly. Goku and Freeza were absolutely exhausted by the time they eliminated Jiren... So that tells us how exhausted Jiren must have been as well, given that the duo essentially overpowered him.
Jiren is retardedly powerful, but it's hard for me to imagine him *still* being above Vegito-level at that point. /shrug
