I got to think CZR would benefit the most. IGT second and MGM/BYD third. I think CZR can leverage the WSOP brand to give them a leg up. Plus they have more properties in various areas as more states open up to it, or better yet, if the much talked about Federal Bill were to pass. CZR's Facebook page is pretty clean and easy to use....Doubledown's is a little too cluttered for me. Will be fun to watch play out.
