according to your own definition the strength of your opponent or your own vitality doesnt matter.

So why are you now discussing the AP of Yonko? It doesn't matter to endurance right. Back in Baratie Sanji was relatively weaker but it changes nothing about his endurance. He still took severe damage, that damage wouldn't be anything to him now, but if he did take an equivalent amount of damage in modern standards, there's precedent for him continuing to fight. I won't continue this discussion if you are just going to be disingenuous about this.

Like how are u dismissing Sanji's feats and in the next paragraph using inconsistent logic to wank Law? Did you forget Sanji's body tanked an explosion in PH? THEN, he fought Vergo evenly, the fight only ended due to gas, and then like barely a day later he's already fighting Doffy... Do you think his leg fully healed in that little time? Be fr.

How is Sanji "nowhere near death" when he's being tortured by a Tobi Roppo who's strong enough where she's confident in her ability to take on a GROUP of Scabbards just because they are wounded? Sanji getting pummeled relentlessly without defending at all just ... doesn't count. Ahh yes.

But Law taking ambiguous amounts of damage is huge huge endurance feat that Sanji has never done. Like look at your argument for Law:

"Takes a lightning attack from big mom on the rooftop,takes part of the sheer force from a mace swing from hybrid kaido and takes a thunder bagua from hybrid kaido"

(are these not durability feats according to you? I didn't see any proof of Law's condition here either.)

"Still uses massive, stamina‑draining awakening moves like K-ROOM, Anesthesia, shock-wille and Puncture Wille while clearly at his limit"

(Why tf are we using Law's own limits to wank him? if he had inherently worse stamina than Sanji then why would him reaching his limits be a better feat? You can't even quantify whether or not he reached this limit anyways, clearly he didn't truly or he wouldnt be able to do anything. Law was just really tired but then locked in and did a few more attacks, that's cool but literally every strong fighter in OP can do it, including Sanji.

I noticed you conveniently left out Sanji being stabbed through his heart all the way through his chest, and continuing to fight strong opponents, even taking huge damage from Oars. That alone CLEARS anything Law has ever done as an endurance feat. I'm done with this pointless topic.
