I've had no major issues since switching back to Comcast (from AT&T Uverse). The performance and reliability is much better than Uverse is (or was) at the time. Pricing is comparable (one of the reasons I switched back), though I'm not sure that is either a plus or a minus. The only issues that I have encountered have been during the weekday, though they have not been major issues, but they are concerning when I'm working from home (VPN, softphone, VDI...). All in all, I would suggest Comcast's services in my area in as a whole they are providing the best service.
