I absolutely believe that zoro being equal to sanji doesn't make sense if sanji has coc infusion just like zoro. Sanji should be above him if that's the case. Likewise, sanji being equal or stronger than zoro is detrimental to zoro's character. Story wise it shouldn't be. Raleigh and Gaban being equals or close to is okay because there's no context about their dreams and aspirations prior to becoming pirates.
In the case of Zoro and Sanji things are different. Zoro is pursuing a goal tied to strengh. He wants to obtain a title that will put him in a category of relevance that very few people in the show can compare to. For instance, pirate king is a title, world strongest man is a title, world strongest creature is a title, world strongest swordsman is a title, etc... These titles are something given to characters that are a level beyond their sobriquet such as dark king, mountain eater, black leg, etc... They are a status displaying a level of importance and achievement in the world of one piece supposed to separate those who have them from the rest.
Now Sanji's goal is not to get a title just like Gaban and his strength should be of or above Gaban's. The issue here is that being locked in the "wings " system means is growth will always be limited by zoro's and it's a shame because by all logic if he were to unlock king's haki then that should give him the edge over zoro. And for zoro, the limitation of being a "wing" means that no matter what he has to be relative to sanji whereas his title should put him in a category of legends such as Ryuma ( who has been associated with joy boy) and thus in a level of strength different from Raleigh, Gaban and Sanji EOS.
