For the typical in-home wall runs, this isn't necessary or even useful.
Actually, with the higher speed data, and having choice what room to locate a cablemodem, quadshield is the ONLY choice.
I'd pull a fish tape with each incase something else is needed in those rooms...but that is me.
Perhaps if you live next to a TV transmitter or if there is a $3 difference between DS and QS cable or you're buying less-than-high-quality-cable-from-China (read: copper-claded center core). The better built DS cable will smoke the cheaper built QS stuff floating around on the web in the interference rejection department. Or you're running 300-500 foot runs (which then you should step up to RG11).
Otherwise, there's no need for QS in a home.
As far as data speed - DirecTV recommends RG6 solid-copper-center-conductor dual-shield with 60% braid coverage or better, swept-tested to 3 GHz. Even though they only use about 2.1GHz of that. Your cable modem isn't going to get anywhere *close* to using that kind of bandwidth (DOCSIS 3, with 8 channels used is only using 48MHz of bandwidth).
As for personal experience, I've installed 3, 1000 foot rolls of Perfect Vision DS and have yet to have a problem. With any of it.
edit - I, apparently don't know the difference between your and you're. Fixed it.
edit #2 - Comment on cable modem BW and here's a very good read on QS/DS cables:
