I agree Wano's pacing was absolutely odd, but that might've been due to the schedule and that the arc took years to come to its climax. It's possible that Oda may have rushed it, or that he was asked to add things that slowed it down, which would explain why the anime did what it does best.
I wasn't here for when Skypeia was in the works, I just know that it was a hated arc for a long time because of how slow and filler-ish it felt in real time. Wano was clearly not filler in nature (despite how much of a difference there is between Wano and Onigashima itself), however, I can't deny it felt slow at times. I think it'll flow a lot better on re-read, and that it doesn't take away from the rules of the world, some fans might've confirmed this.
In terms of ranking favorite arcs, I don't know if it'll personally be in my top five favs once all's said in done, but for sure it has one of my favorite One Piece moments. The wait was absolutely worth it.
