At the time of posting this, I have two favorite drones. The DJI Phantom 3 Pro has been a rock-solid performer for me. The 4K video has been silky-smooth and although I did have a few troubleshooting challenges (drone technology is still in its infancy, so it’s to be expected in my opinion) but never one that I could not successfully resolve myself. With that said, on today’s market I feel that the Phantom 4 is the best drone! The overall build quality of the Phantom 4 is superior to the Phantom 3 Pro, the gimbal seems to be more stabile and it more internalized and it features new features like obstacle avoidance, enhanced battery life and a visual tracking feature. Both are great drones! If cost is a concern, there is nothing wrong with choosing a Phantom 3 Pro in my opinion. It likely won’t disappoint!
