Well, the reason i ignore the 360 as a gamer is that it doesn't offer much compared to its big brother the PC: pc gaming hardware has become a lot more resilient to the passing of time in recent years, meaning you don't have to upgrade that frequently in order to have decent performance anymore.
Much of its purpose is to bring PC gaming in a box and its edge is lost, it is a 6 year old machine, the comparison is simply crushing, frankly on any settings.
Plus i hate playing shooters with a mouse.
