Beginning of Wano till about chapter 980 was pretty good for me.
Onigashima gives me mixed feelings. It had all the usual pacing issues, the excessive fake deaths + still can't fully enjoy Nika's fighting style.
On the other hand I enjoyed a lot of stuff in the raid, I just love advanced Haki and DF Awakening focus. Zoro vs King became an easy pick in my fave fights and Luffy vs Kaido was amazing pre-G5. Yamato could be better, but she still was a good addition IMO.
Anyway... Wano sure is problematic in many points, but not even close to make me quit.
