So Yonko/Admiral level ish is your estimate?

I hear you on the Mihawk ting but personally I'd argue that Zoro's ceiling or rather floor is Ryuma and not Mihawk so he's not really bound to Mihawk's level kinda like how Luffy is not bound to Roger.
Also I wouldn't really sleep on Shanks tbh. His gas is incomparable to the rest of the Yonko particulary his Haki gas. Moroever he said to have defeated Loki which is looking a bit mad atm but then again it's Oda's golden boy Shanks.
On your Yonko/Admiral level estimate though, where would you rank Ray and Gaban then? If Zoro and Sanji are going to be in and around Yonko/Admiral level? Coz I'd argue Zoro and Sanji are going to be significantly stronger than those two EoS.
