Eric Cheng's book "Aerial Photography and Videography Using Drones"is a valuable resource.
He covers a lot of ground, and there is a lot of ground to cover when you discuss everything from toy drones to learn to fly with, to large octacopters with full frame DSLRs aboard.
For most of us, a quad copter is the best set of compromises in terms of size, cost, capability, safety, utility.
One point that many folks are unaware of, is that many of the cheaper drones do not offer complete or even any control of their camera from the ground remote control.
If you are truly interested in photography, you need to look at the cameras and their ability to be controlled while in flight carefully before purchase.
The DJI Phantom 3 and the Inspire do offer almost total control of the camera functions from the ground. The Phantom 3 does not allow the camera to gimbal to the right or left, just up and down. The craft has to be yawed right or left to turn the camera.
The Inspire adds a gimbal movement to the right and left and allows a pilot AND a photographer to simultaneously control the aircraft and the camera, as opposed to a single individual performing both functions. This may or may not matter to you, but if it does, it influences your purchase choices.
Many GoPros are not controlled during flight, just turned on and let run, without the ability to alter exposure or framing during flight. Your drone may need to offer some sort of interface to control your GoPro and to extend this control to the ground remote control. Many of the older drones do not offer this feature. You just turned the GoPRo on and then flew. Not the same as a camera with remote controls. If you need manual exposure, not auto exposure, and you frequently do when flying, this can be an issue for some folks.
I am still learning to use my Phantom 3 Pro, but it is easy to fly, and I can shoot video or stills in manual mode, and I can use polarizing or neutral density filters as needed.
As for being an #####hole, most folks never even hear the drone once it is above 50 feet, and I only fly it away from people anyway - my interest is aerial scenery and landscapes, not imposing on other folks privacy.
I think of my drone as a camera with a very tall tripod! It can capture some nice images if used appropriately, but so can most cameras if used with some knowledge and skill.
