I've played rental VCDs that no other CD-ROM, DVD-ROM or CDRW can play without skipping.
Unfortunately, it's hard to get your hands on a Yamaha these days.

Asus drives are bad with scratched discs. Lite-Ons are average.
About these tests at CDRLabs, the MSI MS-8216M DVD-ROM was supposed to read scratched discs pretty well. But that drive doesn't. I had it for a few days, it couldn't handle my rental VCDs, so I sold it off within a week.
IMHO, the tests on a drive's error correction capabilities at CDRInfo seem to be accurate though.
