Till now i still prefer Jap Subs compare to Dub probably because i have grow following subs from the first time i watch anime and also i believe that Jap Subs have more life inside. As i have played some games and sometimes i just can't help but to stop playing some of the game because of the terrible dub.
In Japan becoming VA has become some kind of prestigious occupation but probably in U.S.A this kind of thinking haven't been spread everywhere. Well this is just my opinion and how i see them so if i am wrong i am sorry lol.
Dubbed anime gives me a dizzy feeling whenever I watch them, maybe because I got used with subbed animes.
And I can read the subs over and over again whenever I can't understand some dialogues, rather than listening to their dialogues over and over again - because it takes too much time.
