I'll pick 360. Better games, more support, and such. The only bad part is the RROD, and having pay to play Live.
PS3, doesn't interest me at all. I don't need a blue-ray. I only have about 4 games that I want to play, there's barely any games you can play online with, and I really don't like how the fanboys act toward other consoles.
Here's the games I want to play that's PS3 exclusive:
1. Drake's Fortune
2. MSG4
3. BlazeBlue/Project BB
4. Warhawk
FF13? I don't like the FF series, and don't like Square Enix that much. I find the new FF games bad, and really don't interest me.
Motorstorm is just too short and nothing to do after awhile. I can get a Forza Motersport instead.
Resistance? Why would I get a PS3 for a FPS, when the 360 has better ones?
Heavenly sword? My friend beat it in 4 hours. He even returned it.
Rachet and clank? Don't really like the series.
Lair was a disaster.
The 360 has, DOA 4,DOA 5, Ninja Gaiden 2, Alan wake, Gears 2, Halo wars, Banjo three and a few other games that I want.
