Kaido fought the whole alliance for 60+ chapters and did nothing... while....
Akainu, in just 30 CHAPTERS of screen time, manipulated Ace so he can roast his organs into ashes, tanked more than 30+ pirate boats buster hit, mercilessly shooted magma fists at hundreds of pirates, melted a straying Marine subordinate, fucked up Luffy's mental health & gave him a neat chest scar, insulted and eliminated the worlds "strongest man" and still had the enough strength fought Crocodile + 12 WB's commanders all by himself.
Oh, and have I mentioned? He also defeated another admiral named Aokiji to achieve the Fleet Admiral position.
Akainu is the true goat
