This is a generalization that may or may not apply to the area in question.
In most all areas, Comcast passes local HD without additional compression in 2:1 QAM, and they also pass some national HD channels, like ESPN & TNT, without additional compression in 2:1 QAM.
Other Comcast HD channels are 3:1 QAM, which come from Comcast Media Center, and can look very good depending on the state of the system they are being viewed on.
Other cablecos, like Cablevision and WOW, use 4:1 QAM.
In A/B comparisons between Comcast and DirecTV that I've seen, Comcast looks better on all HD, especially the locals and 2:1 QAM channels. Again, this may depend on the Comcast area you are viewing in. And of course it may change when DirecTV gets it's new satellite operational this spring.
