I have it and it has been rock solid. We have a 12mbps plan and it’s plenty to run our Netflix account.. It is DSL, so no difference there.

The nice thing about DSL is that nobody else is sharing your bandwidth. With cable, even thought the max speed possible is more, you’re lucky to get close to that during peak times. We had COX internet and it sucked ass. The cable modem kept crashing, and forget about getting on the internet during a football game. I think it was a signal gain issue. COX kept telling me it was my splitter, and eventually I had the line dropped from the pole plugged directly into the modem and it would still crash. Switched to DSL, and have never had a problem, and I’m paying half as much. One issue, however, is that the speed on DSL is dependent on how far from the hub you are. We’re lucky and live just a few blocks from the big AT&T bunker on College Ave. I use a DLink DIR-655 router btw.
