My god guys, its almost like how YCs arent equal, Yonko and Admirals arent equal between each other and their own factions.
Yes, ofc Akainu is stronger than the other admirals. Its also very likely BB and Shanks are stronger/more capable than BM/Kaido.
Lets not beat around the bush here. Kizaru is getting focus in an arc after 2 Yonko. His danger to the crew may pose a bigger threat than these 2 Yonko did, because thats Shonen progression.
However, that same shit applies to everything else. If Kizaru falls here, then BB, Akainu and Shanks are more dangerous threats in their own way. If BB or Shanks were next, then Akainu is more of a threat than either one of them. If one of the Yonko are the final antagonists, then they are stronger than Akainu and the other Yonko in their own way, and potentially the strongest in the series sans the MC who defeats them.
