Powerscaling based on feats is stupid shit.
If we base powerscaling on feats, Lucci > Kizaru since Lucci one shot Sentomaru and lasted longer against Gear 5 Luffy.
However, we all know that Kizaru > Lucci because of narrative.
It's the narrative that determines the powerscaling and not the feats.
That's why admirals = yonko is wack in the first place when the narrative is putting the yonko above the admirals (WSC, WSM, WSS, JoyBoy, Shanks, multiple devil fruit eater) and Oda has already introduced the Gorosei who are stronger than the admirals.
