Yeah, last I checked Thor is still the All-Father so he should stomp, I think it was said that he surpassed Odin not sure which ish it was, it was during the Herald of Thunder arc iirc. FSF wouldn't work since Thor could just take his power back like when he did with Galactus' power cosmic to force himself back into being a Herald. Something even Galactus didn't think was possible. He also has different types of hax and has a natural self-sustaining power source whereas Vegeta has a finite pool of ki that defines how strong and durable he is depending on how much fuel he has in his tank (And if his fights with Recoome, Frieza, or Cell is in any indication he's pretty wasteful with his ki supply when he tries to overkill his opponent). They're also cosmic-god universe level characters fighting on top of a fragile planet that Vegeta needs to survive via oxygen, so that's another disadvantage. Yeah I'd say Thor takes this. I'm not sure what universe x busting level Liam's gonna give them this time. If Thor is under x3,600 universe level than Vegeta will have the dc advantage.
