I agree to an extent. It's just a weird middle ground. Like you have people like Marco fighting Kizaru casually, but you also have Akainu doing it with Whitebeard lol. In both instances where Marco and Akainu lost, they were jumped on when they were distracted.
I just find that interesting. I think Admirals being closer to Yonko is a good guess. I think Kizaru would have best Marco anyway obviously, but I'd question if Kizaru could beat Kaido let's say, depending on how that matchup would go. Not saying he can't, I just wonder if he can
