I'll even up the replies for we have Dish service and for the most part it was the DVR service that got our attention which included the latest model DVR(Dish DVR 522) which came new,free of charge and installation was free for 3 TV's.
We we're Directv subscribers from I think 1996 right up to 2004 when we switched services,at the current time we see no reason to switch back,the constant thing of Directv changing cards was getting annoying,Dish on the other hand doesn't require cards for the receivers was another selling point for us.
If you're into HDTV,Dish has 30 channels of HD which will be our next upgrade to hopefully this year but shopping for the right TV is going to be an adventure-popcorn
