Vista is said to match mihawk though
And Mihawk is said to Surpass Shanks
Said to have been waiting for someone to surpass Shanks
Directly called stronger than Shanks
Calls Shanks one armed has been.
Zoro who low diffs Marco is still trying to surpass Mihawk.
So where does that leave us?
Where as Vivre Card Data book said this
"Although Vista knew he was weaker than Mihawk..he was still not afraid and his swordsmanship was able to match Mihawk in Marine Ford"
They are just saying Vista matched Mihawk in Marine Ford where Mihawk isn't even using 1% of his strength and Vista still knew he's weaker
Same data book said Mihawk isstronger than shanks
