Well, about the only thing we can conclude from this thread is that rotor quality is hit or miss and different people have widely different experiences with the same rotor. Brembo came up here as a high quality rotor, yet a few here have said they have had negative results.
Another poster stated "Worst: Chinese rotors from Advance or Autozone. Short life, quick warp, lots of fade."
Yet, search the Auto X (Cross) forums and there seems to be a cult following of AZ Duralast rotor users. For instance, at this site:

"I've been running Autozone front rotors; part # 34203 for the last four trackdays. OEM and Brembo blanks stress crack after about that many days of hard running, so I figured I'd give these a shot."
Years ago, my daughter had 3 sets of OEM rotors replaced under warranty on her Grand AM for warping. After warranty, I installed AZ Golds and the problem never came back.
Go figure.
