No. Ace surpassed him. In MF when Ace was out of commission Oda still didn't highlight Vista along Marco and Jozu. Marco and Jozu were introduced together by stalling the Admirals 1v1 while Vista was introduced in the same panel as Rakuyo and Curiel and the other commanders.
Vista only attacked alongside Marco when Jozu was defeated. Had Jozu been around he would've attacked Akainu next to Marco, that's undeniable.
Mihawk factually couldn't overpower nor dominate Vista. It would take him less time to one shot Vista than to actually ask him for postponement.
Fake news spread by whatever provider you had lol and I'm hearing there's even more that was hidden but let's wait on that.
