I prefer "open levels", like Medal of Honor: Airborne, where you're dropped into a level (in that game, with some choice as to where you drop in) and have to complete your objective(s) with several available routes.
Combined with destruction physics, there could be some amazing opportunities, if we had some devs with some balls (and funding).
Open world by itself, though, only works for certain types of adventure games, and requires a lot more work to make the world feel "alive."
