I don't have TY CD-R media, but the Kodak Ultima Silver+Gold 12x CD-R that I have left are manufactured in 1999 and they still burn great, although only at 8x (or 16x depending on the drive).
My preferred CD-R media are:
Verbatim DataLifePlus 52x
Fujifilm 52x Made in Germany
It can depend a lot on the drive and burning speed though - the Verbatims are fantastic at any speed in my NEC 3500 and Matshita UJ-840 drives, and at least as good at speeds up to 16x in my Plextor 712. They are good at 32x in the Plextor but not so good at 48x in the Plextor. With earlier firmware in my Plextor they were unacceptable at 32x and 48x, but great in the Plextor PX-712 of a friend of mine.
The Fujifilm burn really well at all speeds, but still have more C1 errors than the Verbatim regardless of which of my drives I burn it in.
The flip side of the coin:
The least impressive brand-name CD-R media I have experienced, which are still being sold, are manufactured by Moser Baer India as 52x rated, and I've had these under the Imation brand and also as Verbatim DataLife Extra Protection Surface. They don't produce coasters, but they are almost impossible to burn without getting C2 errors when scanned in my Plextor drive. Maybe the Plextor just doesn't like to read these?!
The point of my story is: Even the best media may not be optimal in your particular drive at all speeds, so find out what works for you in your drive (or selection of drives).
