As we know,One Piece is a Shonen manga,so its target audience should be teenager readers,altough,as it is a very old manga,it also has many older readers,who grew up with the manga.
But,Oda often stated that he still writes the manga with a 'young boys' audience in mind,altough,who knows if thats true or not.
By the way,if we think about it,altough teenage readers surely love Zoro and him being a badass,i think they can also relate a lot with Sanji. Lets see,how are teenagers usually?
-Horny as hell (Like Sanji)
-They often argue with their parents and act rebellious (Sanji hates his biological father Judge,and altough he cares about his "real father" Zeff,they had a kind of dynamic where they often argued with each other)
-Sometimes they get discriminated (Like Sanji was discriminated by his brothers)
-Everyday they find out something new about theirselves (And Sanji is probably the Strawhat that discovered things about himself the most in the post-timeskip)
So i think that,altough the teenage boys surely adore Zoro and see him as a role-model of physical and mental strenght,and they can also like Luffy and see him as a "funny friend" who takes you out of your comfort-zone,Sanji is probably the character more "relatable" between the three of them. Sometimes he feel like a loser,something he feel cool,like many people,also in adult life
