I think that Billy is the best as well. It's just my personal preference though.
Welcome to PEEL, Worble
eh.. I'll link you to a thread where this question has been asked before :Who is your Favorite Voice Actor?
Most threads already exist, so best would be to search for them before opening another one covering the same. That's also why your thread here will probably be closed soon, just because there is another one for the same topic.
Peel has few guidelines, that searching before opening threads is one. More of them, toghether with tips about PEEL and its behaviour are comprehended into a little FAQ, the PEELers' FAQ
. You should take a look at it.
After all, enjoy your stay here.
