Verizon FiOS is, very surprisingly, decent. Of course when compared to Comcast, the bar is pretty low. And compared to other Verizon offerings, you'd think FiOS would be shitty but it is honestly very refreshing.
Anytime I've had to call for an issue, it was fixed within a reasonable amount of time. One time it was some sort of speed/connectivity issue and they figured it out at the neighborhood junction within a day and another was to bury my fiber and that was within a week.
Comcast charged me for a technician to come out each time. I had to fight that charge each time. Took MONTHS to get that fixed.
