The next step would be to determine the criteria for rating the systems. Maybe someone can suggest some criteria for rating and we can all rate the systems that we've had or used. But that brings up the later point, how many people have both systems?
Without a control group, with everyone having both systems, and both systems bought at the same time, I don't know if we can get a good representation of which console is "best".
But that's just me!
