Saying dubs are bad outright is a bit of an overstatement, there are some good dubs out there as well but they are usually left for films or big budget anime series. Slayers has a awesome dub So does Yu Yu Hakusho, they are from the 80's and 90's so I can assume QC was at a much higher standard back then.
Code Geass and Death Note share are also acceptable dubs.
