Scott,
Have you considered getting Verizon FIOS and ATT U-verse so you could compare those also. Are they available in your area? I think it would be very informative sitting and looking at all four broadcasting the same program and get a comparison.
There is probably 99.9999% chance that you'll never see FIOS and U-verse available in the sam area. Verizon and at&t each have their local service area, no overlap, for pulling copper/fiber to a home.
