Originally posted by KentoSSB Vegito "rivaling" Beerus was mentioned in supplementary material outside of the manga, iirc. As for Broly: if the movie is more in-line with manga canon(which honestly seems to be the case), then Goku did watch Beerus fight all of the other Destroyers simultaneously during the Exhibition Match, so he would've at least had that in mind when he mused that Broly was "probably" stronger.
The problem with Broli and Vegetto statements were in the fact they came from people who have never really felt or seen his full power. So while Goku and Vegeta fusions can rival what they have seen of Beerus, its really not a thing until Whis or someone says it.
But either way, all of that is rendered moot with the revelation that Beerus could have apparently destroyed Angel Moro at any time, with ease... It's akin to how BoG heavily implied that Beerus was using very high percentages of his power against n00b-SSG Goku, yet we later learned that was obviously not the case, and he was really just using micro-fractions of his power the entire time.
Ever since DBS began, Beerus has been scaled up to transcend whatever level Goku is currently operating at, with literally no explanation. Toriyama just loves Beerus, and obvs wants to keep him as the strongest.
Originally posted by KentoIt would be more in character for Goku to be referencing raw strength/power when he mentioned that Moro-73 was the toughest opponent he's ever faced(because that's how Goku always measures his opponents) -- hence why he also asked Moro if he's ever trained, etc. So if we assume that Moro-73 > Broly(as Goku indicated), then it implies that current MUI Goku > SSB Gogeta by proxy.
Also doubt MUI Goku is anywhere close to > SSB Gogeta. It just doesn't make any sense. Because that would mean that MUI would times Gokous power by what it is. Goku says he never came across anyone as tough as Moro but, Moro has so much esoteric abilities like ki drain that it makes sense he would say as tough as him.
MUI Goku stomped the christ out of Moro-73 with no discernible effort whatsoever, and could have casually destroyed him at his leisure if he wouldn't have gone full-retard... Moro literally had to amp himself with the power of a trainee Angel to put him on par with MUI Goku.
Flip side, Broly soaked absolutely everything that SSB Gogeta dished out, and just kept growing more powerful the entire time. Moreover, it would have taken Gogeta's most powerful attack(ie. a "full force" Kamehameha) to put Broly down for sure.
tl;dr
MUI Goku stomped(and could have killed) a more powerful opponent in Moro-73, with less effort than SSB Gogeta stomped(and could have killed) Broly.
...That's my interpretation of it, at least. /shrug
