I seriously doubt that DirecTV will offer more HD channels than Dish for a number of reasons unless things change drastically in the HD distribution/availability chain. For one thing - Dish still has exclusive rights to the VOOM channels and that represents quite a few channels. And for another - most if not all of the "new" DirecTV channels that are planned are stations (like discovery and some of the movie channels, etc.) that Dish also has agreements with so I'm assuming that when DirecTV gets them Dish will also - unless some of the new birds don't make it up into the sky. Dish has always prided itself in offering the most HD channels in the industry and I don't see them reliquishing that any time soon without a fight.
I actually have both Dish and DirecTV (minimal DirecTV in order to get the YES network - one of the very few personal gripes I have about Charlie Ergen and Dish) and I also have friends with the DirecTV service. I can say, from personal experience, that I consider Dish technical support and service far superior. They aren'y even close in terms of response and othjer issues. For example, the DirecTV installers fraudulently double billed me for equipment I never ordered almost a year after the fact and it took some work from American Express to catch the perpetrators. Another example is a side by side comparison regarding the quality of SD offerings. DirecTV is just plain ugly and Dish is tolerable. And, based on what I've seen, the Dish HD PVRs just blow away the DirecTV PVRs in terms of features and functionality. And don't get me started about which of the two satellite services compresses their signals more. HD-lite has become synonymous with HD-DirecTV.
Yes, I would agree that both DirecTV and Dish are far better options than cable (at least here in suburban NYC) where CableVision defines the term "incompetent." And if you are a rabid sports fan who must have your NFL ticket and several other exclusives, then DirecTV is probably the way to go since you have no choice. But before we start annointing DirecTV the King of All HD Media let's see them get it right at least once.
In a related matter, I understand that FIOS TV from Verizon will soon be active in my neck of the woods (I already have FIOS Internet and it is superb!). The day that this happens I will dump my DirecTV box and get YES from FIOS instead. Then I can see how FIOS fits into the pecking order of TV and HDTV serice providers.
I'm a DirecTV user (reluctantly, as explained above) and certainly not the president of that company nor of the Men's Hair Club.
