i own a ps3 and a 360, i had the 360 for a while and only got my ps3 about3 months ago but afterfinishing killzone, uncharted, and r2 i havent touched it.and after a 3 month break from the xboxthen going back to it i realized just how good the games are(gears 2 is jawdropping after plaing ps3 for 3 months)if you own multiple consoleswhich platfrom do you get the most out of?

I use my 360 the most but my PSP and PS3 are not far behind.
