In general, lighting is PS3's strength, but they don't bring that up here. As multiplats made for 360 first it would make sense to be slightly better, but it still doesn't make PS3 less of a graphics king I say.
Everyone else always says the Ps3 has better visuals on GTAIV. The Orange Box shouldn't even be here due to the obviously highr 360 quality (I got it for the PS3). I think GS is slightly biased.
