Dish is actually pretty decent. It's my main viewing source and DTV is used only for the Sunday Ticket (yes, I have only the Sunday Ticket with DTV and have had only the Ticket from DTV for years).
Personal choices, and mine is that in general, I don't like DTV, and I have tried it for extended periods, twice, but poor equipment flexiblity (I like Dish Network's dual tuners.) pissed me off and DTV quality is no better, and may actually not be as good.
