I like Nero 6-8 simply for one reason; they have an audio equalizer. If I apply the 'rock' equalizer to my MP3's (metal/rock) when I burn, the outcome quality is noticeably better. Percussion and guitar is much more noticeable.
That's a pretty neat feature BigDogChris, I may have to check that out. As someone who listens to a lot of metal getting more bass out of my tracks would be a nice touch.
With that said, I use CDBurnerXP as Demon10000 suggested because it's so lightweight and easy to use.
