Doesn't change the fact that Chopper fought a stronger opponent than Franky which is the point. By this same logic, Oda could still be saving Jinbe for later on in the arc, like he did Franky on Enies Lobby.
Usopp annd Nami taking Ulti's headbutts is easily PIS and if we wanted to strain the argument we could argue she held back with Nami for instance as she was trying to break her spirit and with Usopp, well we've literally seen his skull crack before and he didn't die lol.
Ulti clashed with Luffy. Luffy!! in an headbutt clash and pushed him back. In the same clash she proceeded to force Luffy to use G4 and he'd have done so save Yamato interfering. Took a Raimei Hakke (which imo is an attack that utilizes advanced CoC) and tanked that shit. Took a combined attack from Linlin's homies (i.e. the strongest attack Linlin has shown to date and prolly has in her locker) and tanked that shit and was defeated by Nami in weakened state and coz of an insane PU upgrade in Zeus. Ulti who was on her last legs, managed to dodge the Raitei mind you, and was only hit coz it was a homing attack.
In comparison Who's Who barely managed to hurt, Jinbe and ran like a bitch tings got peak for him, had his strongest attack tanked by Jinbe and ultimately got beaten by Jinbe mid diff at best. The man is a disgrace and has nothing on Ulti and I say this as one of his ex-biggest fanboys lol
Hence my further explanation.
With CP9, we had a fool proof way to make a hierarchy, heck Oda did that for us by literally stacking the Douriki numbers on top of each other. And sure, there could be further factors like DF mastery, the level and type of Rokushiki they mastered more and so forth, nevertheless sure thing. That´s the reason why we know Kumadori, even if by only 10 Douriki, was stronger than Fukurou.
Without that? You can´t claim you would have known.
From the fights, Kumadori was completely overwhelmed by Monster Point Chopper, whereas Fukurou did some serious damage to Franky, with fists and so forth. Just looking at how the fights went without Douriki, you would only have feats, and Kumadori was completely at mercy of Monster Chopper, whereas Fukurou vs Franky was an open fight.
Kumadori looked the same as WW vs Jinbe, completely outmatched. Yet you know Kumadori is the stronger one, and him looking like that vs Monster Point, someone who completely outclasses normal Chopper and Kumadori, is not an argument for Fukurou > Kumadori.
I am not gonna argue PIS since it´s pandora´s box and everything can be called that.
I have seen several times the argument regarding the headbutts, since when is Luffy´s headbutt a significant measure to assess her. Luffy´s normal Hardening is neither noteworthy, nor is his headbutt ever been a significant asset.
And base Luffy with G2 and G3, unless he gets out advanced Haki stuff, is still at best a low high tier.
Yep, those are good durability feats, the best for F6, no argument there.
But since when is durability the only factor?
That´s Jinbe for ya.
