TY media generally has been more stable and reliable, especially when being able to burn it at higher speeds (ex: 24x Fujis can be burned at 40x). I believe that TDK is now using Ritek for their spindles but there could be some TY in there too - just always look for the Made In Japan on the spindle .. some other people in the forum have some tips for finding TY media too, I'll leave that to them
Bottom line, if you want TY media, then go for Fuji... guaranteed TY, and plus they're on sale this week @ Best Buy. Can't go wrong.
