DRONE WAR: should you buy a Gopro Karma or a DJI Phantom 4?

The Gopro Karma has just been released and is an attempt to regain a share in the drone market that Gopro earlier lost because DJI put their own cameras on the Phantoms.
How does the Karma compare to the latest Phantom 4?

You can buy a Phantom 4 (or other products) directly from DJI with discount here: http://click.dji.com/AA8VJwGKsvKEytix8MM?pm=link
