I have followed one piece for 10 years already. It is always my favorite anime. You have two options whether to read manga or watch anime and choose which medium you are most comfortable with because you can read manga at a faster pace while anime much slower. One Piece is a manga which gives special attention to its characters. It has some of the best character development in any manga or anime.There’s a great plot in One Piece, and a rich, whimsical setting in the Pirate Age, but the reason One Piece stands out is neither of these, its because its characters are some of the most memorable and important in all of manga history. It has so many chapter and episode but you can consume at your own pace so you will not get burned out but if you already watch first 25 episode and didn't like it at all you can just stop. Maybe, this might not be kind of anime that you like and try other popular anime instead.
