the Xbox 360 version of Red Dead Redemption possesses higher resolution, improved levels of detail, noticeably superior performance in-game and fewer jaggies owing to a more consistently applied anti-aliasing solution that doesn't blur the image. Shadows are generally sharper, and of better quality (particularly on the characters' self-shadows).

In short, Rockstar is to be commended on what is an absolutely fantastic game on both platforms, but the technical analysis is pretty conclusive: if you've got the choice of buying the game for either console, Xbox 360 is the version of Red Dead you should buy.
