Paper we never once heard who won those duels. Mihawk and Shanks tied and then mihawk refused to duel after he lost his arm, either because he doesn't want to clown on him or because he doesn't want to lose to a handicapped dude but either way you can't say who is stronger 1v1.
We only know Shanks > Mihawk because Shanks has one of the most respected crews in the world and a bunch of territory and and Mihawk has one island, a raft, and some candles.
He travels on that raft and not even nature can fuck with him.
While Shanks needs crew mates, helmsman, navigators etc to deal with Storms, Mihawk on a raft deals with them with his advanced CoC.
Thats actually a reasonable assumption no

We know New World and even Paradise, natural disasters on Sea are insane, they basically wiped out shikis fleet. Mihawk has no jolly Roger, no sail, no helm, just a little raft.
He probably controls weather with his advanced CoC
