I used to have Verizon DSL, but since they decided to put me on an overloaded circuit I would experience 25-50% packet loss during peak hours. Now I have cable internet now, and 99.9999999% uptime (network goes down once in a blue moon for a short period).
Guess it depends where you live in relation to DSL service, how good/reliable the company is, what platform they are using, etc.
If your current cable internet works great, don't switch.
