Which anime do you think has the best dub, and the worse dub ?

[DARK OSAMU]

Well since it's MEANT to be a Dub I have to say the best are both vampire movies...Vampire Hunter D Bloodlust and Blood the Last Vampire.

Worst would be anything DragonBall (really anything by FuniMat).
Trigun has an UN-GODLY DUB as well. I think it ties with DB.
Gokudo has a wretched dub.
Tekkaman Blade 2 has a terrible dub.
Gundam Wing has an annoying cast of "VAs".

I think I will stop now because I don't want to get on a roll...
