You have to look at the video and audio: the SID is still to our day one of the best analog 8-bit generation synth chips, the VIC-II pushed 8-bit graphics to their logical extreme.
NES and SMS both had separate video chips that where not programmable from the CPU or shared the RAM in the same manner. Also the C64 had software that you could copy!
Finally the C64 has more releases today than the PC, the Apple 2 has maybe one release every 2 years: http://csdb.dk
Maybe I should have added "with audio/visual quality".
