1UP ran one of these earlier, and now GameSpot has its own feature. Be sure and check it out.
I am working on a feature/review of all the cross-platform PS3 launch titles, this should be online by Monday.
In short, the PS3 games are "lighter" and "foggier" when directly compared to the same game on Xbox 360. The worst case offender right now is in Tony Hawk's Project 8, the 360 version has gorgeous HDR, and the PS3 version has rather harsh, nasty, HDR.
