Those are not drones but FPV system you can build or buy and fly
Drone and system
DJI Avata with DJI goggles 2-> Beginner FPV Drone (NEW) (slow and cinematic)
DJI FVP with DJI goggles v2 -> Beginner FPV Drone (OLD) (fast but not so good in low light)
Walksnail HD FVP system -> Cheaper need solder skills and this setup can work with a several drones (intermediate)
HD-zero FPV system -> Cheapest with focus in race (advanced) with low latency
What is your goal? fly inside, outside, race, freestyle, long range, cinematic....
This last 2 fav systems can be used with several drones from 2 inch to 7 inch but you need to have solder skills and time to build and tune.
Good luck
