x box 360 vs PS3

Modern Warfare 2 is a outrageously great game in which i have recently on tuesday bought. It has great multiplayer and campaign gameplay. On the PS3 there are better graphics and free network. But for the 360 you have to pay for x-box live and the graphics aren't a good. But then again there are more players on x-box live than there are on the Playstation network.
On multiplayer i am currently level 14 and have unlocked a bunch of trophies, and guns. My domain name is titaniumspork (I was doing my chemistry HW and eating food with a spork when i was makeing a name for myself.) In a normal game i would have about 10-15 kills sometimes less depending on my teammates. Sometimes my teammates are douches and try to steal my kills or follow me and give away my position and get us both killed. I use the SCAR with red laser scope. The annoying thing in Modern warfare 2 is that you can not use vehicles (except the helicopter, but that's hell of cheap and you need to have a 9 kill streak to get it.) My 2nd favorite weapon of choice is the M4 with grenade launcher because its easy to kill people with it. I don't know why but when i play online, im mostly the bad guys and never the good guys. What i like is that when people camp they think that they are so good but there is kill-cam which shows who killed you. You can simply go back and kill him/her. ( I suggest that if you are sniper never to camp.)
Well i am off to my PS3 again and will get to lvl 70 and get all the awesome weapons now. lol :)
