I don't know what I would rate this fight tbh... in terms of fights in Wano specifically, I think it's near the top if not at the top. The only thing I can think of that would top it are the earlier fights like Zoro vs Killer (the art especially for the finishing panel was better) or the whole Rooftop battle
If I were to compare it to fights in the series as a whole I still think Zoro vs Daz Bonez is a better fight
visually. The art back then was just that much better (unfortunately) so it's kinda hard for any current fight to stack up to the older ones.
The Zoro vs Daz Bonez fight literally contains some of my favorite panels in all of manga
I can see what Oda was going for with the King fight but it just doesn't hit the same due to the art
Overall Rating: 8-8.5/10, still one of his best fights in the series
