Depends whether we're going with the manga or anime version of the boost, as well as which version of Super's continuity we're using. In the manga, the boost is a lot smaller, with there not being much to suggest Vegeta became much stronger than Ultimate Gohan. With that boost and for an Anime Super gauntlet, he'd probably still lose to Universe+ level characters such as Infinite Zamasu or Hakaishin Toppo. With the gigantic boost from the anime, he'd probably solo everyone apart from Zen-Oh, who's basically been treat as unbeatable by DB standards thus far.
For Manga Super, either boost would allow him to solo Super apart from Zen-Oh.
