.... he agreed that the only two reasons to use RG6 Quad are a) you're wiring inside the building at the base of the 350,000 watt TV station transmitter, so you need that little extra shielding, and b) the next installer to come along can't look at the perfectly good foil and braid and lie to the client by saying "Oh, I see they didn't use the good stuff, that thicker RG6... yeah, QUAD!"

There is a very good reason to use Quad that is legit. "Distance". That quad shielding has a lower resistance per foot than others. Most spec sheets will also show a little less loss per foot.
Makes a big difference when pushing the limits of a signal out 300, 400 feet or more. And getting voltage out the same distance without significant drop.
In those situations, the center conductor becomes the primary limiting factor. With the outer conductor doing little to increase the limiting.
