Did you just compare Mihawk to a whole yonko crew lmao
The argument is Mihawk vs Shanks not Redhair pirates, but I guess you can't separate these two so you're right
Shanks beats everyone in the verse because his crew wouldn't leave his side
Cross Guild and Red Hair Pirates are probably going to be the competition with the Straw Hats for Laugh Tale and Pirate King. Blackbeard probably has King of the World aspirations if he's really inherited Xebecs will like it's been foreshadowed so that will be the final war and real EoS fight.
Croc not only had an actual logia, he had logia awakening. Dehydrating things into sand by touching them? That's awakening. Its croc's version of turning things into mochi/string, but its much stronger.
If Croc even has decent haki, awakening alone should put him over Katakuri imo.
