I can't speak for everyone and can only talk from my own POV, but here's what I think and why.
First a little background: I got the first Phantom when it was originally released. Expensive (not for the time), no camera, no app, no limitations. I flew it for a bit, put a GoPro on it. Pictures were okay, but video was jello garbage. Sat out of the hobby for a year. Got a Yuneec 4k drone. Crashed it on my second flight. Replaced it with a Typhoon H. Huge bird, huge controller, great video (to me), great pics, limited range. I love the drone, but it is a pain to transport just due to the size. Great in wind though because of how huge it is.
Picked up a Spark purely from a size perspective. Fun little drone. Somewhat limited compared to others and the flight time sucks, but still a good little bird.
Got an Air. Really nice video. Range isn't nearly what is promised. No Fly zone issues. Battery life not great, but can't argue it is an upgrade from the Spark. I like it, but have had more problems with it compared to any other drone.
Got an Evo. An upgrade from the Air in almost every way. Only quibble is it is a little lacking in specialty shots and there have been some firmware issues.
Got a Karma. Never would have got it except it was basically free with purchase of Karma Grip and GoPro 6. Would never recommend it, but it is fun to fly. Has zero sensors to prevent flying into things or for landing. Image quality is great, except you have to process 4k to get rid of fish-eye. Range is garbage and I don't trust it, but it is a fun drone to fly.
With the above said my Evo is my goto bird. I'll often go out with my kids and fly multiple drones, but the Evo is always one of the ones that gets flown. It is easy to fly, fun to fly, takes great video and pics. Has decent battery life, good controller, have had few if any issues with it. The things of note are that there are almost zero 3rd party things available for the Evo. This includes alternate apps, cases, tablet holders, etc. For the most part you are stuck with 1st party items or items not custom tailored for the Evo. There is now a tablet holder available (Lifthor), but it is 4 times more expensive than tablet holders you can find for other drones. I have it and it is great, but pricey. My case is a generic case that I adapted to fit the Evo, compared to getting laser cut cases for DJI drones for 20 bucks.
I love the Evo. If I had to recommend a drone for someone in that price range (Air/Evo/Anafi) I would suggest the Evo. It is a little more than the others, but I think it is worth it. With the 900 deal with two extra batteries and props it is almost a wash with the Air fly more bundle.
