I think the question is compatibility of the media rather than quality,
and I'll explain why. I have had some no-name media which would not burn
for anything in one major brand (brandA) burner, but were totally reliable
in brandB, and after burning read fine everywhere. Since I've gone through
many of the major brands I won't quote the names, both burners are
generally satisfactory on other brands.
The point is that the problem was in the firmware, not the quality of the
media. Kind of like pizza toppings, the quality may be fine, but there may
be some you just can't handle ;-)
