OK I tried the method of letting it land on your hand, and I tried the method of turning off the downward facing sensors (which is three clicks and a drag to get to that switch) and here is my conclusion: Grabbing that thing while it's moving down, and you are committed to grabbing it because it's heading down, is more dangerous. Once you pull down the stick you are having to grab it while it's moving, and on the Mavic in particularly, the props are not far from your hand under any circumstances. Turning off the downward facing sensors is kind of a PITA. Since I anticipate only having to do occasional hand catches, I'l going with the "turn off the sensor" method. If I had to do it very often, though, I'd probably practice more with the stick down and let it land in your hand method.
I don't like the "grab it from the front" method because you have a lot less to grab and there isn't much to grab anyway. With that method you are holding a drone with spinning props by less than half of the body (so you don't get in the sensor field) while trying not to touch the gimbal, and that's not a secure enough grip on it for me.
My old P3A was easy because you has the landing gear to grab and therefore some reasonable distance from the props.
