No experience, but it IS going to be the next stock I buy, probably for my AR556, I like the reviews it has received on midwayusa.
The extent of my Hogue grip experience is the two over mold grips on both my LCP's and on my P91DC from 1993. The rubber on that P91DC still feels as fresh today as it did when it was new unlike my limbsaver on my Reminton 700 which turned all sticky and gooey feeling after about 10 years.
Put one on an AR I built last year. Nice stock and I love the Hogue pistol grips for ARs. I bought it in a clearance bin, it had apparently been ordered special and the customer backed out, so I got it based on price, not features. I'd happily buy another.
