User blog comment:Grievous67/The best and worst dubs of One Piece (Top 16 dubs)/@comment-26082375-20150902052422

I like watching things in whatever language they were first made in, whether it's animated or live-action. In the case of One Piece, that means Japanese, so I watch it almost exclusively in Japanese. It helps that I know enough of the language (and know the series well enough) to be able to watch episodes without subtitles and know what's being said. That said, I have heard bits of the 4Kids and Funimation English dubs. Goes without saying that Funimation is way better.

Touching on what Ryu brought up about Japanese dialogue sounding more natural than English because of not understanding the language; Japanese has a lot more syllables per second than English does, but imparts information at a slower rate. People are talking faster and taking longer to say things, which is reflected in how long the character's mouth is moving. Having to use the same animation of the character talking and forcing English speech to match that same duration is probably what causes some of the "unnatural" sound of English dubs.
