In all reality, they both have their place for different reasons. I personally like having a cropped body at the track or for sports as you get the extra throw without having to lug around bigger than a 70-200mm for most cases. ISO is only one aspect of the shot. If the others aren't setup correctly...you could have all of the ISO capabilities in the world and still have grainy shots.

As an astrophotographer, I have never seen someone shoot that small of an aperture. I stand corrected.
