Though there are several services out there that do pretty much the exact same thing, Comcast’s Xfinity stands out from the rest for a few different reasons. Overall, they boast comparatively high rates of customer satisfaction when compared to their competitors. This makes sense to us, as their streaming service is one of the best out there.
