The weight, size and quality of the DJI Osmo Pocket can't be beat. It only weights 116 grams (4 ounces) and fits in your pocket. The Osmo 2 is 485 grams (17 ounces) plus the phone.
With a full size gimbal, you have to get it and your phone out, mount your phone, start filming and everyone is looking in seconds. On the other hand, you can slip the Osmo Pocket out of your pocket, start filming and most people won't even notice you have a camera. If they do, they'll ask you about it because it's the coolest thing they've ever seen.
And yes, the Pocket takes excellent video.
