How is xbox 360 security for MW2, COD4, W@W?

Hey, I just bought an xbox 360 slim from Amazon.com and call of duty black ops, and it is very addicting. XBOX LIVE is way better for online gaming, it is known for online gaming because millions of people PAY to play. PSN is free therefore the online will not be as great because you get what you pay for. There is no lagging on xbox live, it works extremely fast especially if you buy the xbox 360 slim with integrated wifi inside. There are many apps for xboxlive. PS3 is a great system too but more of an entertainment system. Bluerays are great. However when it comes to buying third party games which can be sold on both consoles more people by Xbox 360 games because they are known to have better online experience and yes better frame rate and graphics. PS3 is good for bluray and exclusives, thats it, otherwise the PS3 does not compare gaming wise. Xbox has exclusives too. Because WE PAY FOR XBOX LIVE MICROSOFT CAN AFFORD WAY BETTER SECURITY AND FIREWALLS AND ALL THAT FANCY STUFF. I say make the switch. youll be happy
