depends on which anime for most anime the American screw up the voice because they dont care, no effort nothing.
Most english dubs compared to the original is complete garbage sounds like fandub or maybe hate dub i dont know
but there are a couple of good dubs e.g. DBZ, Naruto (PART1, part 2 sucks bad) and Bleach
overall Japanese Dubs>>>>>>>>>>>>>>>>>>>>>>English dubs
because they put out more effort in to their work until the American who don't care most of the time because it isn't superman or batman there dubbing,if it was it would be close to perfect
the one piece voice acting (english dub) is great too very good work, sounds almost = to the original,Funimation big money will make people care.
