Nikon Z50 VS the DJI Osmo Action Camera

Testing the Nikon Z50 and the DJI Osmo Action for video quality and image Stabilization.
Can the Nikon Z50 shoot video as smooth as the action cameras Rocksteady Stabilization shooting handheld?
Can the DJI Action camera produce the same quality video as the Nikon Z50?
I mounted the DJI Action camera on top of the Nikon Z50 to find out in this shoot out head to head. Both cameras are set to 4K 30.
I used the first version of the DJI Action camera as this is what I have.
I will be buying the new version 3 action camera soon and will do a new test if I can get a good copy of it. I see many videos showing many of then have a focus problem. The new version 3 now supports 10bit video and even more advanced image Stabilization. So the video quality of it should be a step up from this older version.
The music in the video is made by me just a little background jam music.
