The rule of thumb always seems to be that original works will always be better than its altered or remade counterpart. The same can be applied to an anime that gets licensed for the U.S. market. Usually there are studios who dub over the Japanese voices with English ones. Luckily, if you are not a fan of the dubbed voices DVDs and Blurays offer the option to keep the Japanese track and turn on the subtitles. You can enjoy the anime as it was meant to be enjoyed.
