Damn guys, can we just drop the whole Admiral vs Yonko argument? It's been pretty clear from the start that Admirals and Yonko are by varying levels slightly stronger or weaker than one another, and aren't scalable until we see when they fight first or last
This is a shonen, so Kaido/BM going down first imply they are the "weakest" Yonko by virtue of Blackbeard and Shanks being later opponents for Luffy if he's meant to fight them. Titles do not matter.
If Akainu is a later, major fight for Luffy, he's more "dangerous" for Luffy than Kaido or BM. If he fights Shanks or Blackbeard before Akainu, then Akainu is more dangerous than them. If he fights them after Akainu, then they are more dangerous than Akainu.
That's how it works. The 3 subordinate Admirals are likely weaker than Akainu, because they have lower ranks and Akainu beat Aokiji. So while i expect them to be "closer" to Akainu or Yonko than YCs, they'd still be "weaker" in terms of presence because they are probaby reserved for Zoro/Sanji as subordinate fights, etc.
We literally can't know who's stronger than who until we know who Luffy fights next after Wano.
