By comparison, in more than two years of having a PacBell DSL connection, I have never been down as long as two hours, except once when my router fried its little silicon brain. Friends tell me this isn't a problem with current installs. You are doubtless interested in speed. In casual use, they are quite similar in speed and both are very acceptable. I am typically getting about 1 mbps on the DSL connection and somewhat faster on the cable modem.
Upload speeds are a third to a half of the download speed.
Your mileage, doubtless, will vary. CNET also offers a bandwidth test that can give you an idea of your speed. Finally, a vendor site I like does a more complex test , which I use for comparison. I will not go out on a limb with a recommendation. If you lived next door to me, I'd probably tell you to get DSL, just based on my experience.
