Yeah, at first you think HD is universally good and the same, but after a while you will learn more about it.
As I understand it, Comcast and the other cable companies are pretty much forced to compress the HD channels because they are using all of the available bandwidth on the coax for the "analog" channels. These take up more bandwidth per channel than digital, and so they are trying to get everyone to switch to digital, presumably so they can offer more HD channels (with compression no doubt).
I know for sure that Verizon's FiOS has more bandwidth to use up for HD signals, but I don't know how much they have elected to compress them vs. Comcast.
