I haven't tried FIOS yet, because it hasn't reached my area....but I intend to switch from Roadrunner/Time Warner as soon as it gets here. Whatever you do get, if FIOS isn't available, be careful about getting locked into 2 year or more commitments...the cable/dsl companies are in a big panic over FIOS, and are offering great deals, but with locked in time commitments, to avoid losing customers. I have never once heard of a FIOS user who had a complaint.
