Well, i like a few.
Nero has a good quality, and it is very fast.
Sonic Record Now has an awsome quality, but it takes very long to burn (it verifies)
I think NTI sucks. its spee dis ok, but quality, no way.
Nero is very simple to use, espically for CDs and DVDs, Sonic Record now is quite easy too, but a little more complicated then Nero. NTI is in the middle.
So, which one i recomend? Well, if you will be able to leave your PC alone while it is burning, Get Sonic record now. If you are kinda in a hurry, well, use Nero.
