They probably haven't been around long enough to really prove the test of time. However I have had the Ninja DZ401 for 3 years and we have used it almost daily. Edit: rephrased after having my coffee
I have the ninja af400 dual basket and I love it was looking at this one to replace the big one but I did stay with my af400. Ppl are talking good about this one on the pic.

You’re definitely overthinking. I use an air fryer for lunch everyday so we bought an Instant Pot 10 quart air fryer and it gave us trouble almost from day one. The controls were flaky, and not responsive and the door was a terrible design. After a few years we swapped to a Ninja DZ401 Foodi 10 Quart 6-in-1 DualZone XL 2-Basket Air Fryer. We’ve had it almost a year and I absolutely love it.
We just got a new air fryer, Ninja foodi AF400uk dual zone 9.6L. We were gifted the smaller 7.6L AF300uk about 6 years ago, which was brilliant, but we wanted something a bit bigger. I got it from the Ninja website when it was on offer a month or so ago and you can get an extra 10% off your first order if you sign up to them. Paid about £165 for it. We use it almost every day for a family of 4.
Can’t go wrong with ninja products. I have the duel basket and it’s great. It is somewhat large, but if you have the space, it’s worth it.
How many are you cooking for? I recommend the ninja AF400, pretty much bullet proof and just a great air fryer.
