I'm not gonna lie here.
Zoro fanboys wank Mihawk so hard because they want Zoro to be Yonko level at the end of the series, not realizing that he will only end up being YC1
Comparison between Mihawk and YC characters and Yonko
Firstly, let me show you how big MF was and how big the iceberg was
The island of MF is a lot bigger than people think it is, check the size of battleships next to it and distance angles showing how big it is, and then check the fact that the iceberg dwarfs the island itself. And then check the fact that Mihawk, without a proper stance, made a casual swing, that then made an air slash, that weaken over distance, that then traversed the said distance, cut the iceberg, made of Aokiji's ice, caused it to go up and shatter.
Compare that with the following
Angry BM using a named attack with a proper stance
Note, how BM with a proper stance named attack and a wind slash failed to obliterate the tree in front of her and eventually left a tiny hole in the mountain.
Notice Mingo, a YC level character, upper echelon of it, using a named semi serious kick barely destroying two large towers.
Next compare the size of the slash Mihawk sent
It is barely stopped by Jozu, who possesses a df designed to counter swords, and even so he ends up being bruised and struggles with it, even going so far as to hype himself up before trying to stop it. Still ends up bruised. Similarly to steel, you need to aim to cut diamond to cut it. Note Daz stopping one slash not aimed at him, the next one aimed at him put him down.
Compare the aforementioned slash to a slash produced by a YC2 character, juiced up on her allies, effectively making her stronger than usual, so YC2+ character.
Note how it pales in comparison to Mihawk's slash, and even looks utterly laughable. Note as well, the intelligence displayed by Smoothie, using a vertical slash over and over again, as noted in the panel, instead of a horizontal one, which would have been impossible to dodge. She might be thicc, but she is also dense.
Now, Zoro is almost certainly going to fight King this arc, but he will not be fighting Mihawk until EoS.
