Cable can be quite a bit faster then dsl but it it still subject to overuse by your neighbors. The node shares the bandwidth. Whereas dsl is a straight shot to the central office and rarely bogs down. It also looks like current cable pricing is higher then dsl in most areas.
P.S. A node in this case would be several houses tied into one point for transmission to another point. Several houses could be 1 or 100, all sharing the bandwidth.
