You assume because I asked about sanji I'm one of the zoro fanatics huh? How ignorant, but I'll humor you since I do like zoro better than sanji at least.
His loyalty is beyond reproach. He's one of the calmest crew members and for a long time was the calmest member of the crew. That alone is enough for him to be a more pleasant character than sanji, usopp, Nami, and chopper
Alright then well i guess it’s my turn
People like me like Sanji because he isn’t a typical character you’d find in manga besides the “strong and pervy simp guy” trope. Sanji is one of the most unique characters you’d ever find
Hes a chef who’s capable of competing with the very strongest with only his lower torsow is a unique fighting style that solely involve kicks+is very tactical and smart outside of his gags. Not only that but he’s purely kind hearted and is willing to feed anyone who’s hungry, enemy or ally alike
I will admit his pervy gags are ass at times but like i said, his positives outweigh his negatives
He’s also the only character that can be used in: cool, gag, chad, bad, rad, clutch and badass ways that no other character gets tbh
