There really isn't that much to choose between them all.
I use Nero, Roxio & ImgBurn now but have used VSO previously but I can't say I've seen much difference. I just use what suits me best, eg if I've got an image I use ImgBurn, if I copy a disk directly I'd use Roxio & for compiling & burning a DVD movie I use Nero.
The most important factor by far is the burner, the media you use and the health of your PC (DMA enabled, defragged regularly etc), beyond that it's whatever you're more comfortable with.
That's my opinion anyway.
