From all I have read it is just as accurate as a standard barrel with no down side. If you like the looks, go for it, but honest to God I don't see any advantage of it over a standard barrel of equal weight. One could possibly claim it cools quicker but I don't shoot my barrels hot, EVER, so it would serve no advantage to me other than being something different. I have toyed with the idea of getting one for a kicks and giggles build for over a year, and if they drop the price back down to what it was 6 months ago, $165, I still might, but they bumped the price back up a bit and that kind of turned me off on it. I am not really crazy about doing any more 5.56 builds anyway. GM barrels are outstanding barrels though. I have several done on GM blanks and all are super accurate so the only question in my mind is, do you want the finned look or not?
