I dunno, it's a sticky topic. There are definitely things which are better on the PS2 over the PS3, like the library of games is epic, probably second only to the PC itself, plus some of the best games of the decade are on the PS2.
Though on the other hand, some of the other best games of the decade are on the PS3, plus I have free online, internet acess, ABC Iview, PlayTV, amazing graphics and a music player all rolled into one.
I reckon that all in all, this generation is better than the last. The PS3 has incredible capabilities over it's little brother and the 360s controller is excellent compared to that massive glob of plastic they called an Xbox 1 controller.
