360 or Ps3 graphicswise?

Hey, I am lookin to upgrade from 'zee' Ps2...gettin a little tiresome with the same graphics...I wanted to get a second opinion as to what system has better graphics...i've played the 360 quite a bit at a friends house....looks sweet but i havent really had the chance to see the graphics on the Ps3...i've read about the "Cell" being way more wickeder and stuff, but I wanted to know from someone hands-on. All feedback would be greatly appreciated
