Zoro pulling 100 times bigger feats than Sanji has been a recurring theme since egg-head..his feats and portrayal always parallel Luffy and Sanji is just dumped with the remaining fodders.
It was there with Lucci defeat
It applied in their Gorosei fights
It applied in fighting Gaban
And it also applied when Gaban, the guy who is supposed to bring all the glory to Sanji, was glazing Zoros CoC and saying there are three people in this Island who can defeat a Gods Knight and one of them is Zoro and Sanji acted like a simp right there "sUrElY iT iS mEee"
