I use it all the time, to the point where I am disappointed that not all apps support the gestures for links. I try to peek at a link in Twitter just to bring up the share sheet. I use a 6S+, and I could see where on a 6S the problem of your hand getting in the way of the content could be a larger deal, but you can move your finger horizontally after pressing to get it out of the way, which is useful.
