I've been using these picks (or the Fender counterpart) for the past 10 years and it's a dependable pick. Initially I started off with the green one and then tried all of them out (from thinnest to this one), and I've settled for the 1.14mm because it's durable and because, apparently, I like rigid picks. The light ones have always irritated me because they bend against the strings.
I usually play them flipped to the side (with the pointy side towards the bridge) and very slightly angled, which gives a nice dark tone and the pick doesn't get 'stuck' in the strings. It also makes pinch harmonics easier for me.
I've used them successfully for shredding on an electric as well as on acoustic guitars. They work great for complicated strumming/picking and they are very durable in the face of heavy acoustic guitar strings.
They do tend to slip off every now and then from between your fingers, especially if you're a bit sweaty, but not too much. I don't think I've dropped one while playing sober in the past 7 years or so.
Overall, this is a very dependable pick.
