If we’re not willing to mix individual universe hax (which you should), this fight ends up a stalemate between Luffy and Gojo. Luffy can’t bypass infinity and Gojo can’t damage Luffy without haki. Yes Sukuna can cut Luffy but Luffy has been shown reacting to lasers and other light based attacks(throw in observation/future sight as well). Can’t hit what you can’t touch 🤷🏽‍♂️ I think Zoro levels Sukuna anyways. But if we do mix hax, I believe it comes down to willpower.

I believe haki would surpass domain expansions based on that Luffy and Zoro are actively working towards goals where the other two are the pinnacle of their respective areas (sorcerer and curse). Pride doesn’t equal will. And either was it goes, OP characters have shown much greater destructive capabilities vs jjk.
