My list would run like this:
Verizon FIOS, as long as they have all the networks and RSNs in my area in HD at rollout
The fact that DISH Network leads in the poll at the time of posting confirms the slant on this board.
I've been happy with DirecTV, there's better quality HD and more of it than Comcast here in Atlanta. Not sure if they still partner with Bellsouth/AT&T around here for a bundle discount because I don't have a land line. The boxes are better than Comcast as well. No experience with Dish HD, or Fios/U-Verse but I believe the telco ones have limitations on how many HD channels you can tune...
I do not want anything bundled; EVER! I have seen way too many nightmares AND with a bit of research; I can equal or beat most bundled deals and get better service with exactly want I want and how. The ONLY thing going now I would change is my $42 6mbps DSL for FiOS 15 or 30mbps for a bit more money.
I've had cable (4 different providers in the span of 5 years...same address) and Dish. I haven't had Direct. Verizon isn't even offered But based on the fact that the HD offerings are about the same (for what I watch), combined with the dual-tuner mad-on I have, Dish wins.
