*listens to goku and vegeta's japanese voices*
nope! original VA was pretty terrible.
You have things mixed up, the actual acting in the Japanese is far better than the dub, but the voices themselves are far better in the dub. Sean Schemmel is a lot better in Kai acting wise compared to his first run through of the series.
I think a lot of people get this mixed up in debates like this, there is a difference between the actual acting and the voices they use. Laura Bailey for instance is a very good at acting in her own right, but she uses the same voice 90% of the time. When she is very capable of changing it up.
