Here on the edge of the digital cliff, I feel schizophrenic even trying to judge. I see a huge improvement in quality, but a disastrous plunge in reliability. Raw channel count has made a huge leap (from 10 to 25+), but variety has plummeted. I now get 7 PBS channels, 4 weather channels, 5 religion channels, 3 Spanish channels, 2 ABC's, 2 CW's, 2 ThisTV's, a Korean Channel and an infomercial channel.
The above wouldn't be so bad, but I completely lost NBC, Fox, and MY, while CBS, and one each of the ABC's and CW's are pretty unreliable.
Overall, it probably has been an improvement, since my pre-transition reception was pretty bad, but an agonizingly painful one at that.
