I went from the Standard 3 to the Spark and instantly got rid of the 3. There is no comparison between those two and the Air is even better although not as much better as the 3 to the Spark. I'm not too pleased with WIFI but I haven't used anything else. I agree on the $$$$$$$ issue of drones. Used could be good or really bad. Another factor is Batteries. The more expensive the drone the more expensive the battery. Flight time is not a biggie with me. I get bored after about 10 to 12 minutes and if I'm filming something I try to have a plan and I video the entire flight.
