Depends on what you want to buy a drone for really. They have drone races, drone stunt competitions, then using drones as camera platforms (still or video, live or recorded, First Person View (FPV) or point and shoot).
Then you get into sizes, accessories, and portability. Fixed wing or multi-rotors. Actually wheeled drones are just now becoming commercially available
I have about seven different multi-rotor quad drones, from toys that fit in your palm (indoor flying and terrorizing my cats), larger stunt flyers (some indoor and some outdoor models), to camera platforms that carry GoPro's up for still and video shooting. I've been flying RC for 40 plus years and drones are just the latest trend. I still have planes that are 20 years old and still flying. Some of my early drones are just pieces awaiting reuse...:banghead:
