Honestly, the anime isn't even good. Like, I'm still reading the manga, but I had to stop watching the anime something like 10 years ago.
I've heard it has gotten better since then, but watching the whole thing still includes years worth of episodes so thinly streched you could probably watch every third one without missing anything. And that's on top of arcs so long, they are even a slog to read through (Dressrosa and Wano).
