Not on the same level as Bebop or Black Lagoon, but Death Note easily has one of the best dubs out there. Brad Swaile's Light is just awesome and I don't care what anyone says, you can't watch the show without hearing L's dub. The guy's voice just sounds so natural as him, it's almost scary.
If it all boils down to it, though, you can always watch the first episode in both languages, just to see which road you'd rather go down.
