Won't deny anything here. But Thing is as far as titles go we have nothing to back any of them. So far only WB was wanked so far as "He could Destroy the world". And using what little we have for each character we can safely assume the only reason Prime Beard was considered the WSM even thou Roger and Garp were alive is him having that fruit.
I am curios how do rank the titles? I think
WSM is above WSS and WSC because of that fruit.
My short "why" is i am ranking them this way.
WSM = Power that can Destroy the World - the user is one of the top tiers and can be fought off but has the edge over them.
WSS = The Strongest Blade - the user arguably "should" have the strongest 1 shot attacks against living things. Other than that unknown.
WSC = Strongest Physical Body out of everyone around the world - the user can be stopped by Shanks and can be destroyed by the WSM fruit.
I wouldn't go so far to rank those. Unless we get rivals for those (which I don't think we will ever get) these titles were given to those individuals
after they had reached top levels. Sailing those seas, I would never draw clear lines of superiority or inferiority. Every battle between members of that class would last for days with an outcome that strongly depended on the situation (one quick wrong decision, an external element distracting one of them, etc.). Meaning the fight, if repeated over and over, could still go either way again - and again only after a 10 day long fight.
I start to think that at this point we have to understand those titles were created because of those top level people.
"Oh look, that's Kaido. He's unrivaled, a literal monster in all terms.
(And since he's not really human but rather some weird creature/oni) let's name that guy Strongest Creature of the World.
Same for Mihawk."Oh look, that's the swordsman that fucked up everyone who ever dared to face him.
He must be the Strongest Swordsman on the World."
Same for WB. "Oh, look. That's Whitebeard. Just a regular human guy but he's literally fighting the Pirate King/ or superstar pirate Gold Roger (depending on the time) on equal terms.
He must be The Strongest Human on the World."
Surely Roger had some title too, prior to his ascension to PK. Surely Shanks has some title, too. One that isn't any less worth than WSS, WSM, WSC, etc.
In one piece, titles don't make people. People make titles.
