My honest opinion, promise. Not point saying Sanji > Zoro since Zoro > Sanji, but saying [Zoro will neg diff King] only to change the goalpost into [King > Kaidou] since Zoro needs extra effort and help (Enma training, Oden's haki, Senzu Bean) to defeat a YC1 just like Luffy needing help to beat a YC1 (Kata's Merienda, Kata stabbing himself, Brulee) is just being unhealthily obsessed about Zoro's powerlevel over any other aspects of his character.
but good take Sanji>Zoro
