I'm researching multi-rotors (drones) for my company, as they are interested in purchasing one for video projects. So far, I'm a bit surprised by what I see offered to vote on, but I guess it really depends on what you want to do with it. For shooting video, you really want an FPV system that allows you to monitor what the camera is capturing. The DJI Phantom Vision 2+ has this feature, but none of the others listed has it. Otherwise you need to buy a separate system and install it on a drone chassis that can carry it.
