I'm just going off of my experience. I have the lowest DSL speed because my mom got it when it was first introduced. DSL is a more reliable speed, but is basically limited. Cable, while less predictable and less consistant, can usually offer higher speeds, again all depending on how far you are from the cable company and how many people in your area have cable. When I moved out, I got cable in my place and its much faster than the DSL my mom has. If you got the dsl pro you talk about, and its the same price, then go for it.
