PS4 is obviously more powerful, and plays the latest games. Overall though, PS3 will be remembered more fondly, as it was a major player in one of the greatest console generations of all time. I don't know where the PS4 will land in that debate over time, but so far all signs point to middle of the road. It's kind of a awkward transition period in gaming going on right now, and I think when all is said and done, the PS4 will be mere footnote in the history books. 10 years from now, what do you think the greatest games and milestones in gaming will come from this generation? I can't think of many.
