Are there fans who truly believe mihawk is stronger than roger?
Admirals are top tiers, if the third strongest straw hat is stronger than an admiral then there will be no point in the story anymore(yes i know you said eos but still doesnt make sense).
We will have a better understanding of how strong eos zoro will be, as soon as we see shanks true power. If mihawk and red hair are equal then zoro will be around that level too. So yes yonko level at best but still not stronger than kaido or prime big mom.
