Sure in that sense SBP has actually important hax compared to Adam, but in context of vs their opponents aka when compared to Sentry I get same vibes. OK elephant in room, Prime has le retcon punch. Aka basically reality warping. And isnt reality warping basically do anything thing? So Prime can do anything? But it doesnt seem like reality warping is actually given full "do anything" thing in VS talks. So we have to look at his other moves specifically.
So what does Prime have besides that? I dont know him well so I def missed something. But preliminary it looks like base Kryptonian stuff, laser eyes, ice breath etc. What else? He absorbs magic and can dimension travel, cool. But like again, compared to Sentry this doesnt seem as much. Sentry seems to have more abilities. And what, you want to count resistances? Sure but Sentry has those too. Some people say this MU depends on Sentry surviving retcon punch. And he has arguments for it. They might not be good but he has them. Which then leads to Prime needing to have resistances to Sentry's stuff. And he might not have enough?
So yes, I will compare it to AdamApocalypse because we have fighter who is unga bunga strong with specific hax but opponent might resist the hax and is comparable to unga bunga AND has more hax the former cant deal with. Sure, the stats being equal is also bad argument but again, it exists. So they can be used. And I kinda think it is realistically possible Sentry can win in DB. And because DB's caper scaling is kind of a mess lmao
