Don't quote me either on this, but I think it's best if you definitely DO NOT pick digital. My dad says a friend saw "The Dark Knight" at a digital showing at IMAX, and that he could see the "pixels" that made up the image on the screen, indicating very very low definition picture quality. As a whole, I would suggest choosing the alternative to the digital showing, just to be safe.
