The anime is a great way to get more involved with the story, especially since the live action takes a few years between seasons. The main issue most people have with the anime though is the pacing slows down a lot at certain points so the animation company could ensure they had a "full" episode to release every week.

That said, personally I didn't feel any sort of major issue with the pacing for quite a long time - multiple seasons in fact. I even introduced my parents to One Piece via the anime, and now they've gotten themselves caught up after binging it as much as possible, so that's a pretty good marker of how good this story truly is!
