high-speed access question

[I am Spartacus]

hey everyone, i'm new to the list.  i've got a question about 
residential high-speed access.  currently, my cable is provided by time 
warner and i have used road runner for about the last 18 months.  i've 
been pretty happy with the service, but next month i'm moving to a new 
house in south olathe.  the cable provider out there is comcast, and i 
understand they offer a cable-modem internet service, but i have never 
known anyone who has used it before.  i'm looking for opinions as to 
whether i would be better served going with comcast for high-speed 
internet access, or signing up with at&t for a DSL line.  any ideas? 
 thanks.
