Zoro's dream has nothing to do with him being much stronger than Sanji, it's obvious that Sanji wil be a monster right behind Zoro, and this will be settled down in Wano and keep showing to be even more clear in the next arcs. Sanji being a Vinsmoke will play an important part on him being strong as hell.
Oda isn't dumb enough to create a random character right down to the wire and make him more important than the main ones for no reason until the very end of the series. You could argue that she currently looks stronger than Sanji, Zoro and close to Luffy (depending on what she achieves against Kaido) and it doesn't mean shit, Luffy, Zoro and Sanji dynamic will never change.
You're trying to say that Sanji's current perfomance against Queen is somehow comparable to Jinbei vs WsW and Sasaki vs Franky
Queen is far stronger than any F6 bruh.
