Nothing at all in terms of content. Except the sony have something called direct stream digital encoding, but i did not notice a difference.

If you ran them through a program to show you there wave forms i don't know if they would be different.

plus as far as i know these CD's are not effected and infected with the sony rootkits even though the disks claim to be copy protected they don't seem to be. They rip just fine from what i have read.

Still don't trust Sony CD's because of the rootkit fiasco. Besides my anthology box got a lot more play in my cd player. The star wars 2 disc Rca is tops but the empire strikes back and return of the jedi have numerous problems that only someone as well versed as goodmusician could explain.
