Tell me plz. which camera better ..?

Dji phantom 3 OR gopro hero 4


and


post here some detail & Camera compare videos

  download the original files to view the quality of the P3 video pre-youtube.com.  The videos are in 4K.  Some rolling shutter is present and very disappointing, however aside from that the quality is quite good.  I hope my P3 is balanced better if vibration is the cause for the jello.

Since the Phantom 3 has essentially the same camera as the Inspire 1 here are two videos that I found that compare the 4k quality of the two cameras.

Having reviewed multiple videos on a 4K TV I'd say DJI's camera is much better. DJI's camera is made specifically for aerial photography, whereas the GoPro is an all around camera.
