xbox is better! 1st, more hardcore gamers play xbox, 2nd, yea no party chat, 3rd, PS3 does not have better graphics, the old backwards compatible ps3s had better graphics because of there linux based processors, and because of there blue-ray compatibly intertwined with linux, now they just suck complete ass.
4th, the reason i now hate sony, Sony is the creators of blue-ray, it was there way of changing the way we watch movies or so they make it seem, blue-ray is not but like 1/10th better than normal DvD's but they were like lets market this as HD sell millions of copy's and make millions, and thats exactly what they did.
5th, The Cell processors that sony uses looks great on paper, but IBM claims 10 to 20 percent yields when they actually try to manufacture it. Your PS3 may actually come with only 7 of the 8 cores working; Sony will accept any processor with at least 7 cores working. And if one of the cores dies...well, I hope your warranty's still active.
6th, Xbox is far ahead on motion technology with the kinect, PS3 pretty much just mimicked Wii, and the controller looks like a dildo with a ball on the end..
Well all that is my reasoning xbox is better... ohh don't forget *cough* lack of games *cough*
