I've been watching it at 1.25x since around post-time skip; the pacing is absolutely horrid due to how it's scheduled compared to the manga. Some people may be able to tolerate it, but after 1000+ episodes I feel like I'm wasting my time re-watching stuff at each episode. The animation can be really great in some important episodes, but even in those the problem is jarring. A perfect example is ep1027.
So what now? I've decided that after the end of the Wano Arc, I'm going to read the manga and only watch fan-cut episodes (like the One Pace project). It is a bad anime? No. Would I recommend it? Pre-time skip absolutely, afterwards just read the manga.
Also, here's a breakdown of a typical One Piece episode:
2 mins opening
1 min recap
30s eyecatch
30s next episode tease
2.5mins stuff that happened in the previous episodes
3mins of still frames panning and zooming with nothing happening
1.5mins of reused frames
1min of added dialogue that consists of screaming and meaningless stuff like "we'll see", "I'll kick your butt", "I'll defeat you"
2min of running around and generically punching random fodder
10mins of actual episode that could be 10% faster
My rating of One Piece: 10
My rating of the anime: ↓↓↓
