PS3, Xbox 360 Super Street Fighter 4 image comparison
Coming from an artist: PS3 is saturated and the colors are very contrasting. 360 is LESS saturated and allows for better detail. There is also more range in colors. Plus, it's easier on the eyes. This came from a person who has a degree in fine arts. In the end, it comes down to personal opinion and what pleases your eyes.....even if your eyes are wrong! :)
