Well this forum is composed of "mostly" North American or UK users. Those areas are 360 turf. So naturally its the more preferred console.
Its just the PS3 minority is waaaaaaay more vocal.
IMO........better online, better multiplats, fewer/more relevant exclusives, XBLA is outstanding every year, Kinect > Move, more timed/exclusive DLC, and 360/PC games (where as a PS3 gamer needs a PC to do what 360 has).
Offcourse my opinion will be scrutinized, but Im used to that.
