I would prefer subbed since I hate the english voices for Naruto. At first I didn't mind it, but after I started watched the subbed on the internet I found dubbed very annoying.
It depends, really for me. I can watch dubbed if the voices are good. Unfortunately, thats not always the case... I would watch Bleach dubbed before Naruto. >.> Death Note dubbed was just okay. -shrugs- would rather have it subbed, now that i've watched the series in both languages.
