FWIW, I have had the exact opposite situation in multiple locations across the country -- every DSL (and, once, FTTH) connection I've had has been rock solid -- every Comcast internet connection has been flaky -- in one place, the connection went down every afternoon. Multiple Comcast technicians couldn't figure out the problem. I so agree with your last statement. If you're in an area they serve, getting Sonic is much better, BTW. They can operate over AT&T FTTH and DSL. It's a tad more expensive, but the customer service is unbeatable.
