Sanji is the butt of a lot of the jokes in Oda's humour, but that has only ever bothered insecure agenda dorks.
Genuine fans of the character find that endearing about him.
They fans that ironically enjoy the agenda bullshitting have been FEASTING Wano, but I would say really since Sanji dipped before WCI.
Oda's turned Sanji into a legit speedster - arguably the second faster character in the series - with an insanely cool and versatile skill set that gives him abilities on par with both Paramecia and Zoan DF users without any of the of drawbacks and weaknesses associated with those attributes.
Normally speedsters are landlocked, physically weak, lack stamina, and attack power - the complete opposite applies to Sanji here.
The only shortcoming Sanji has right now is lacking ranged attacks, but I like that as a contrast to Zoro's "fuck everything in that direction" missile capabilities.
