I've never really been a big fan of Nero or Roxio as they are often very bloated applications when most times you need a simple cd burner application.
I've since moved over to using imgburn. It's free and it works great.
I used to use cdburnerXP...but it tends to max out my CPU for no good reason when I burn disks. I found this being discussed on the CDburnerXP forums...but it wasn't worth fixing as ImgBurn met my needs.
