Sure, I will just follow the reasoning I always follow in this regard:
If Zoro is comparable to Luffy we've all wasted twenty five years of fighting potential with Zoro facing a second-class adversaries; awesome writing there, certainly. Unless, of course, the hierarchy is just like Lucci, Kaku and Jabra, as Oda made it obvious back then, and he will keep feeding this rivalry so the fandom increases its activity (which, again, is of economic interest for his business).
And let's get this right: I do think Zoro is stronger, but I find it highly unlikely that Oda has been working on their rivalry for so long (not only with gags but with actual versus of incredibly close enemies and all kind of hints, like Mohji and Cabaji) only for Zoro to be hugely stronger than Sanji and equal to Luffy. That's just inconsistent and makes zero sense from a writing point of view.
Then you had Oda straight-up comparing Luffy, Zoro and Sanji to Lucci, Kaku and Jabra in the most explicit ranking possible (the only ambiguity actually discussed the power difference between Kaku and Jabra, not Lucci). But certainly "feats" and "portrayal" are relevant here even though the first thing Oda does after timeskip is putting them both in a fighting contest with the Pacifista.
I'm sure Oda wants the community to believe Zoro is miles ahead Sanji and not very close, because that's the narrative he has been reinforcing and not the rivalry that fuels fandom activity to its highest.
