360 and PS3 are basically two sides of the same coin.
At the start of this gen the 360 had everything I wanted. Actual console jrpgs, the 3rd party games worth a damned, and seemingly decent exclusives. I think Alan Wake was the last real exclusive I bought(Witcher 2 was the last console exclusive I bought). The system just felt like something amazing. Chromehounds on XBL was amazing and nothing else out there was like it. Lost Odyssey was and it's ilk really hurt the argument that the system wasn't diverse. And Gears just looked damn good.
Honestly PS3 just looked kind of pathetic. I of course got one for MGS4, but after that the PS3 was mostly quiet.
And then the 360 kind of stooped. Uncharted 2 came out for PS3 and well after that it's been PS3's show. 360 seems to have mostly died off and become boring. MS is complacent with it being a CoD machine and throwing gamer's a bone with it's rotating series of Gears, Halo, Forza, and Fable. All of which are past thier prime or where never that exciting to me.
PS3 on the other hand keeps giving with stuff like The Last of US, jrpgs are at least alive if just playing it safe on the machine, there's a few niche Japanese games outside of jrpgs also still coming out, and third parties seemingly get the system now.
So basically the 1st half of this gen was 360 and the 2nd half PS3. It's a clean cut.
The Wii, well it has some good games like obviously GOTG Xenoblade, but it was never consistent for me.
The PSP was pretty boring until the end here where for me it just seemed like all of a sudden it had all these great games. The PSP really is underrated and it's a shame what happen to it. Had a good amount of it's titles not stayed Japan only we would have had a real godly system.
PC, well I'm a console person and only recently have I been getting into pc gaming. Eh, I don't know.
