Congrats.
I have 2 drones a Phantom 4 and a Mavic.
I started off with Phantom 3Adv and flew it for a while, then sold the P3A and upgraded to a Phantom 3 PRO and flew that one for a few months. I made most of my mistakes when I had the P3 Adv. One day I ran into a very good deal on a Phantom 4 in the classified section of this forum and the deal was too good to pass up and bought the P4 but I did not see that much difference between the P3P and 4 except for the OA. Finally sold the P3P and bought a Mavic, as we speak my current setup is a P4 and a Mavic.
Since the P4 PRO was announced I have been thinking of buying one, the camera is far superior than any other drone in the market in its class.
I like the portability of the Mavic, we travel quite frequently so this portability makes it convenient to carry around in airplanes. I believe the P4 PRO is an awesome drone, perhaps not as portable as the Mavic, but the camera capabilities are incredible.
