Everything you said is completely false.
Every admiral has more showings and better feats than Mihawk except GB and arguably Kizaru.
Aokiji shits on him as a character and Akainu is easily better.
Luffy antagonists? Are you crazy? Doflamingo, Rob Lucci, Crocodile? I can keep going. Mihawk hasn’t done anything character wise.
I won’t name the warlords because half of them are Luffy antagonists.

Mihawk is a more likable character than (as I've already said) akainu, aokiji, kizaru, gb, doflamingo, lucci, crocodile, the other warlords except for jinbe and debatably law. I can keep going, there are so many more characters that are less likable than mihawk. Everyone you mentioned has been portrayed as a total piece of shit, the old admirals have the most boring character designs imaginable, I don't give a shit how strong they might be, mihawk is a far more likeable character even without zoro wanting to surpass him.
