Yeah, ignoring an ISPs bottom tiers to boost the average is manipulating the data. VZ's true average is 5Mb.
As far as speed, Comcast is the fastest major residential ISP, period. Comcast offers a 305Mb service, VZ's top tier is 300Mb. VZ loses. Whether or not people buy a Veyron is irrelevant, it's still the fastest production car. Whether or not people choose to buy the $300 Comcast tier is irrelevant, Comcast is the fastest. It's also irrelevant that the 305Mb tier Comcast is only available in certain areas of their footprint, just as FiOS is only available in certain areas of Verizon's footprint.
You might not like it, but that is reality.
