Goku Black vs. Vegeta

Assume that Vegeta had learned how to activate Ultra Ego during the Future Trunks arc instead.

UE was ultimately a crap transformation, but it still gave Vegeta a massive boost right out of the gate -- SSB Vegeta was low-diff pummeled by Granolah, but once he activated UE, Vegeta stomped the christ out of Granolah initially.

So as long this theoretical UE Vegeta goes for the kill right away, he should definitely win.

UE is overkill. SSBE would be enough to stomp Black.

SSB from TOP would easily stomps Black . UE is overkill
