I use to be very picky about what media I'd burn on.
I'd only used Mitsui, TDK or Kodak.
Nowadays I'll use just about anything that consistently works. And I've found just about everything does. Verbatim, Iomega tend to be brands that still suck though.
We've gone from 4X burners 3 years ago to 32X burners today. The media has got to evolve along the same lines.
Not saying their isn't junk media (or burners) out there. But bad luck is getting harder to find.
I have no probs burning audio at 12X, which is as fast as my burner goes. I don't hear any difference between that speed and 2X. Guess I'm going deaf.
