We're coming over from DTV, and have 1x Hopper3 and 2x Joey's on the order. My question is, are the 4k Joeys faster/more responsive/better than a wired Joey? We do *need* RF remotes for both Joeys, and the responsiveness of the UI is important to me. However, neither of the TV's are currently 4k (and I'm not planning on replacing them, though one of the sets is circa 2008), the coax is already run to the location, so there's no benefit to wireless for me. Putting the Hopper3 at one of the locations (for better performance) isn't an option. It will have to be a Joey.
