Really stupid question cc directv/satellite, etc

Other than more recording channels on the Hopper, what other technology does Dish have that DirecTV does not? You would need to compare a Hopper 3 to the new Genie 2 or similar receivers/antennas. Be sure to include how using having to select Eastern Arc or Western Arc satellites (requiring 2 different LNB's) is better than only having 1 centrally located set of satellites.
