I lost count of One Piece series' episodes, what it's like, 700 episodes now? I don't know if I'll ever be able to watch such a large ongoing show as this one.
At least with the likes of Doraemon, Kiteretsu, Kochikame, Shin-chan and others they do have more than a 1000+ (except Kiteretsu & Kochikame) but each episode is its own story.
I've tried to get into One Piece 3-4 times in different story points.
I just find the series to be boring, I don't like the animation, and the characters are meh to me. To each their own though must be doing something right to have that many eps.
I wish Cased Closed Detective Conan was still being dubbed over One Piece though.
