Should I change from the dub of One Piece to the sub?

Yes please do. I was in the same situation as you. One piece was amazing but I didn't like watching sub. But then I got tired of waiting for the new batch of dubs. So I decided to watch sub instead. Thanks to that I watch all my anime in subs now. You should start off from the 385 instead of watching it all over

I watch dubbed when I like the voices, basically if the main character's voice fits I'm kinda fine with it. (e.g. Death Note, Code Geass), But i watched One Piece in dubbed as well, and when I changed to sub it was something else. No more censorship everywhere, the jokes are much better, it becomes instantly more serious, and of course it's much further ahead than the Dub.

Its up to you. If you wanna wait for them to dub more episodes that's fine. But the sub is way!!!!! ahead. of the dub. If you have time then continue on with sub.

ALWAYS WATCH SUB!!!!! its soooo much better nearly every time.
