It's been 10 years since the Post-TS started and here the list of everything Sanji showed
- Sky walk ( fodder ability that even foot soldiers of BM army could do)
- Hell memories ( HE LITERALLY USED THIS AGAINST FUCKING WADATSUMI IN FISHMAN ISLAND )
so not only was Sanji fighting with Jinbe...
Luffy is the incarnation of Luck whereas Zoro is the incarnation of hard work , he's always nerfed either by injuries or enma or gets to eat the strongest attack in the verse.
Luffy = beta cuck
Zoro = sigma grindset champ
i doubt it , he declared multiple times that his dream is to become the greatest shogun of all times , if he leaves wano he would just be repeating Oden mistake of leaving Wano unguarded from Orochi and Kaido
