So the short answer is it might be closer, but Goku Black would proooooobably still lose. Even in Xenoverse/Heroes the most you can really argue for is multiversal+, with maybe 1 dimension on top of that with some levity(and it honestly takes waaaay more steps to get to that point than DC). DC’s multiverse is much larger in comparison and frankly Zoom would still be stronger if you decide to take dimensional tiering seriously, because of the bleed. Not to mention Zoom has far more “incalculable” speed feats than you can possibly argue for heroes(which has maybe one or two feats, which are contested).
This doesn’t get into the fact that technically Xenoverse, Online and Heroes are all separate continuities. As well as the fact many of the Heroes games/media like the victory mission, ultimate mission X, world mission, the various anime/manga ect are also essentially separate adaptations with similar concepts.There really isn’t some grand master plan that ties this stuff together. It's all fanservice and most of the attempts to connect it all into something cohesive is mainly just fan theory.
The only argument I’ve ever seen is people trying to say Heroes is “outerversal” because the player character in Heroes, “Beat”, Comes from the “real world''. Then that this “real world” looks down upon Dragonball as fiction. But that’s always been heavily extrapolating imo. Beat’s world in heroes is pretty consistently portrayed
as just being a future timeline of Dragon Ball GT, and has cameos, references and so on pointing to that being the case as early as 2012.
Regardless if you have to go this far, it’s pretty clear Black can’t win without some heavy benefits of the doubt.
