Ive got road runner and verizon dsl and I use the dsl strickly for gaming. The speeds are comparable one bit but the latency/ping makes a big differnece.
i wish i could do that but i live in hawaii and unfortunetly in my area we can't get the only other service i guess is out there which is dsl.... it's hawaii telcom which has a verizon backbone so i wish i could try it for now im stuck with roadrunner cable internet and it isn't going well so far
