E* or D*. What does it really matter who promises what. What matters is delivery.. And since both companies are fighting each other for the most, we, as the customer are going to be the winner. I have both at my house. So I am going to have the best of everything they can throw out there. I never have seen the advantage of the "mine is better than yours" fight. In the end, they both are excellent systems with each having an edge in certain areas. And each having certain areas that really need some work..
