As one of the few drummers here, I'll be happy to help you out.
The Superstars over the Rockstars. Superstars are intermediate drums and Rockstars are beginner. So the hardware/shells/ect will all be better on the Superstars. But when looking at the Craigslist ad and also the guitar center link, you would only be getting the drums in either case.
Do you have any hardware/cymbals stands/pedal currently? If not I'd say get the the Superstars. Besides the fact they have been used in Malevolent Creation, they are better drums. Also save about $500-$600 on hardware and cymbals if you don't have them already. That part always sucks, but it's worth it.
If I'm missing any information let me know and I'll help you out.
