I think funimation does a pretty good job personally. I cant stand it when there is one voice that is so grating that it ruins the entire show. Clickenbeard who does kid gohan in kai and luffy's voice........I'd rather listen to the hottest treble headphone than that.
That said many Japanese female VA's are outrageously high pitched.
That said my voice pitches higher in Japanese than it does in English. And my native Japanese friends note they feel they pitch higher in Japanese than they do speaking English as well.
