The voices match the characters and aren't generic voices that you hear in every other anime dub. The delivery is always spot on, too.

One of the only good dubs produced by Funimation, in my opinion. Everything is perfect.

Just...good. Nothing sounds unnatural, the voices fit the characters well. I like that whichever company dubbed this (can't remember) took some liberties to make the show slightly more relatable to its English audience, as most of Lucky Star is based around Japanese pop culture. 

Death Note is...well, it's very dramatic, therefore it's REALLY important that the delivery of voices be good in order for the dub to be even passable. In my opinion, the dub ended up being fantastic. 

I don't like this anime, although I used to as a kid. I tried rewatching it and went to the subbed version by default, but I didn't like it enough to pay much attention to it so I tried the dub, expecting it to be awful. It wasn't. It was actually really good...

I realize this is an unpopular opinion and maybe it's because the dub is what I'm used to hearing as I grew up with Naruto, but I don't think it's bad. Sure, Naruto sounds like a chainsmoker but the delivery of voices is always pretty good, the voices just belong to the character's and the translation is faithful. I dunno, I think it's a pretty good dub!
