The best voice ever was Masako Nozawa (voice for Goku in DB), it was so PERFECT for this charachter and i loved it ever since
Because i like female voices i also really like Paku Romi (Ed FMA) and Takeuchi Junko (as Gon and Naruto). I also loved Hayashibara Megumi as Lina Inverse ...
The best male voices were definitely Ryo Horikawa as vegita, Andromeda Shun (Saint Seyia), also Takahashi Hiroki as Hisoka in Hunter x Hunter (he was brilliant!)
