Warning: long post.
Having been a D* sub for a year and a half after being an E* sub for about 10, there are some comparisons that I think everyone here will bear out:
DISH used to be considerably less expensive than DIRECTV. No longer. I have been investigating going back to DISH because of the high bills from DIRECT and discovered that a comparable package, including number of channels, HD access and DVR for 3 TVs is about $15 higher on DIRECTV, after the promotional honeymoon ends. That wasn't enough for me to switch because DISH does not carry channels I and my family watch frequently, including GOL TV, MLB Network, FX HD and FSE (available on DIRECT's Sports pack; on DISH only by purchasing an additional-cost Spanish package). Would not be enough to offset the gain of WGN and Travel Channel in HD. Plus, DISH's well-known reputation for allowing channels, including locals, to disappear while trying to negotiate the best rates turned me off.
Technology: While I do need additional receivers for every TV with DIRECTV, this is acceptable when I consider that I am paying only one DVR fee for ALL TVs. With DISH, I was told I would still have to pay an additional $10 for the third TV, the same as I pay now. And I was not willing to have to have additional holes drilled in my floors and walls to accommodate the cables needed to connect receiver #1 to TV #2.
Installers: The weakest link for both companies. It has been my experience that the installers in this area generally lack professionalism and have little interest in maintaining a respectable image. Maybe that system works economically for both companies, but it means that there is a wide range of confidence based on however the local company decides to comport itself.
Corporate image: I am a marketing consultant, and I realize that money buys better. However, that is not always the case. DIRECTV always seems to project an image of a well-organized, upscale, professional company. DISH Network seems to have the image of a mom-and-pop operation, or a furniture or carpet store. Perception is reality. And DIRECTV wins the perception battle, hands down.
Customer service: During the last several weeks, when I have needed to adjust my DIRECTV bill and inquired with DISH Network about becoming a customer again, it was my definite impression that DIRECTV's CSRs were the more professional and knowledgeable. Asking about pricing on DISH Network, for example, I got three different answers to what several packages included. I also got three other answers from different retailers, leading me to believe that I was going to get unpleasant surprises when my promo period ended and I had to start paying real prices. I also recall issues when I was a DISH sub, such as scheduling service calls.
So even though I pay somewhat more for DIRECTV, I am getting more of a value for my money. I am not totally happy -- I was not informed about having to extend my contract when I upgraded to HD last September, for example. And there was an issue with not having to pay for an AM-21 off-air receiver when DIRECTV replaced a balky HD receiver that included local OTA channels with a receiver that didn't. (That issue was resolved after many discussions, including a call from DIRECTV, which very much surprised me.)
The bill is still high. But again not much higher than DISH's price for a comparable package and light years beyond anything I can get from MediocreCom cable.
I have no "emotional favorite" -- I will pay my money to the company I get the most value from. As anyone should do.
