plus the fact sasuke didn't even react to sakura getting kidnapped, whereas vegeta would go on a killing spree, I mean he just lost it when finding out future bulma was killed, black goku is in for it now xD
behold the vegeta of dragon ball super:
not to mention shadow wolf in that same interview that he said he mislead us, he verbally insulted us and said we read his story wrong, sorry but I refuse to support some stuck up author like him.
In a fight between Vegeta and Sasuke, Sasuke would be crushed repeatedly no sweat.
