Yes, cope and see how Vista's body is shaking from their clash, unlike Mihawk's body.
Cope and see Mihawk fighting Vista without focusing on him, instead he was focused on Luffy, and still not take a single hit from Vista.
Those are the facts anti-mihawk fans have been denying for years. No amount of headcannon will make it go away.
Now ask yourself, why did Oda put that scene in the manga? It's because he wanted us to truly understand the huge gap between their strength. It's not just that, it's the fact nobody else the manga has showed the capability of facing a character as strong as a YC without needing to focus on them. That's how strong Mihawk is.
Now since I have proven how much stronger Mihawk is with facts let's take a look at the Viva card.
The vivre card was only talking about the swordsmanship used during their battle. It's similar to Zoro's vivre card where it stated Zoro and Lucci we're evenly match. It was only talking about the power Zoro used at that specific time. As the battle went on Zoro was handling Lucci with just two swords.
As I said, it was only talking about the swordmanship Mihawk used during that specific match. Vista swordmanship is equal to a Mihawk's fighting at a low level and not focus on his opponent swordsmanship. Good for Vista.
