In all fairness I also think Zoro defeats King then scars Kaido (using king to get used to enma) while Sanji defeats Queen and does something big in the emperor fight as well so Luffy smashes both emperors.
each taking down 2 opponents in a way
I’m not hating on Zoro? I love Zoro. He’s a bamf but until you can show me a panel where Shusui is stated to have its own power that Enma doesn’t have Youre the one using headcanon my dude. The canon states the slash was more powerful not that the sword is capable of doing it.
