Zoro can mid-diff King and shitstomp Queen, yes. Sanji mid-diffs Queen but gets ragdolled by King just like rooftop Zoro was. Worst part is Sanji gets ragdolled regardless of King's flame being on or off as King's flame off feats still surpass Sanji's. Flame on = absolutely no chance.
Sanji cannot give Luffy a tough fight if Luffy is remotely serious. Sure, if Luffy fights in base without ACoC then Sanji could push him to mid/high-diff (Luffy still wins handily w ACoA and FS), but if Luffy uses ACoC it becomes a straight-up shitstomp. Sanji gets bodybagged by even base ACoC Luffy.
It's a similar level of bodybagging if Luffy uses G5 without ACoC of course, and we don't even need to talk about G5 with ACoC. We don't even need to talk about G2/3/4 with ACoC - Luffy's CQC feats vs Kaido genuinely show that he can handily defeat Sanji in base. He totally outclasses him in CQC.
"Not even Roger could mid-diff Gaban" genuinely where are you guys pulling this from? Where on earth is this Gaban hype coming from lmfao like at least wait for some feats from the guy. We haven't even seen CoC from Gaban let alone ACoC, and if he doesn't have ACoC then Roger is definitely shitstomping him too.
