It's a really bad idea to watch the One Piece anime, period. There is a reason that a remake of the anime has been announced before the manga has even finished. One Piece is a series where the manga is legendarily good yet the anime is legendarily bad.
One Pace only fixes one problem, namely the bad pacing, but the anime has WAY more problems, from non-canon stuff that gets added all the time to actual inconsistencies, etc.
With how long it is, you're just throwing away a huge chunk of your life for a worst experience.
Here's what you do if you wanna get in One Piece right now:
- ignore everything you've heard about OP; it's a series with an astonishingly vocal and ignorant fanbase who downright doesn't read the source material; this is wholly due to its popularity, not to any fault of its own (it's actually the greatest story ever told)
- go to sites like
this one
- read the colored version: it's amazing and it covers 90% of the manga, you can read the last 10% in B&W
- make sure it's the fan-translated one, the official one has stupid translation quirks
- read slowly: OP is the kind of story where small background details from years ago end up playing a huge role later on;
- after finishing an arc, you can watch the cool parts of the anime: fights, reveals, twists, etc. (don't ever bother with whole episodes, the OP story just doesn't work that well as an anime simply because there is too much exposition)
- NEVER read YouTube comments/X threads/etc. about OP until you're caught up with the manga; if you come across (apparent) plot holes while reading, DO NOT GOOGLE anything, just keep reading until you're caught up
- DO NOT LOOK UP ANY OP WIKI UNTIL YOU'RE CAUGHT UP
