Really its close, xbox doesnt have some of the ritchness of colours the PS3 has but then again everything on the PS3 looks very shiny i.e. the soldiers helmets on COD:WaW, there helmets are shiny even though there in the middle of a battlefield with dirt flying around everywhere. Xbox however has good detail aspecially in rocks and floor textures. All in all it comes down to exclusive titles (which i think will become a thing of the past soon enough), what has the better online experience and just generally what you would rather play.
