All I know is that Sanji fans win no matter what.
Either Sanji surpasses an adv coc user and debunks the "only the very strongest" retarded bandwagon garbage haki wank, or he gets CoC and suddenly this place is gonna become Impel Down with the amount of toxicity I'm gonna release here.
This "yamato>zoro" thing is irrelevant, even if it were true, when both Zoro and Sanji are gonna be above Yamato at most by the next round of arc fights.
