If I were to play online with Call of Duty Modern Warfare 3 or even Call of Duty Modern Warfare 2, or even with Killzone 3, would I have a great, action packed, gaming experience just as good as I were to get with the Xbox 360?

Yeah. Both systems are virtually the same, just different companies and features.

Id say ofcourse. One thing i will tell you is dont take any bullshit from any of the microsoft or sony fanboys saying either ones better. They are both pretty much the same. I own both and prefer the games on ps3 but other than that theyre the same. Killzone 3 multiplayer is awesome i thoroughly enjoyed it. Cod on the other hand is getting very old and stale and mw3 has been severely bashed by fans on metacritic.

I own both consoles. I have had an xbox 360 since 2006 and i recently got a ps3 , yea like 3 days ago. I like my ps3 alot better than my xbox. I love that it has free online play and stuff
