I have both. So no bias here. I like my PS3, The controller isn't as big and feels better in my hands. (IMO)
I also don't use any of the "wave you hands" around games, so kinect or move have no value to me.
I do watch Blue Ray movies when my GF rents a movie at red box so thats nice.
I only play online and its completely free which is nice, XBOX has to pay the monthly fee + MW3 "elite" fee.
I only have 1 tv hooked up in my house so multiple tv's are useless.
I rather have my Ps3 then Xbox just because I use it more.
