Originals are always better, be they English, Japanese, German, French or whatsoever. And then, listening to different languages on a regular basis ensures that you don't forget them as quickly (~5 years) as you learned them (providing you know those languages).
On the behalf of anime in particular, I think the Japanese female actors just sound more appealing then the English ones. This is, of course, absolutely subjective and is my personal quirk.
But then my girlfriend is Japanese, so I could understand why.
