Coverage differences in Dish Network vs Direct TV

I am looking into getting satellite TV, and I was wondering whether there was any difference in coverage between the two major providers. I live in a very rural area and I just wanted to make sure that my chosen provider would be able to carry a good signal in my area. Does anyone know whether both providers cover all of the US? Is one better than the other (Dish Network vs Direct TV)? Does either network have better coverage to rural aras? Does that fact that it’s satellite mean that all areas are covered? Any answers would be helpful (sorry for my ignorance, I clearly know nothing about satellite TV).
