Interestingly, my friend Mark was playing the XBO version right next to me. It took me a while to look over and compare. The differences really didn't stand out to me until I made that comparison. Then I realized how much more detail there was in the guns and how the colors in the environment popped a little more in the XBO version (That's the Handsome Collection version).
Oh, and there is differences in the menus. Locations in your list of missions aren't broken down by DLC like in the XBO version and the whole interface works faster in the XBO version.
