That really depends on the company, the package, and the need. I have AT&T's DSL, and have had Time-Warner's cable in the past. To me, there was little difference between the two, especially since I used the "Pro" package from AT&T, and I do alot of graphic and content intensive work online. I also like AT&T's customer and technical support much better than Time-Warner's. You may also want to look at a fiber-optic system, which is faster than DSL or Cable, although not available everywhere, and often costs much the same.
