Probably not the response you want, but in my experience if you have the room and extra to spend I would highly recommend a second oven with convection. I picked one up for ~$50 at an auction and apart from the install and overhead from upgrading electrical I found it killer for when I have a lot to cook or there are multiple people interested in using the kitchen.
I think the air fryer appliance was designed to sell more small appliances.
Don't get me wrong, I adore my air fryer and own a big stupid oversized Ninja air fryer with a grill grate in it that my family uses daily.
But IMO the air fryer is very modern and was designed from the start to be a consumable product and I'm sure my Ninja will die within the next few years.
I've also thought about bying a new oven with air fryer functionality built it, but my spouse pointed out that I'll have to buy a whole new oven when that breaks...
That's the feeling I get about a lot of these smart applicances, kinda starting around the time of the instant pot fad. I love my instant pot though, and it's lasted years. But in terms of repairability, I don't know what I'd do with it if some internal electronics stopped working
I got this one for my birthday and we use it basically every day (2 adults). Absolutely fantastic. We did a super extended reddit search (before API announcement :) ) across dozens of threads and ended up putting all the experiences together and get this based on what we want to use it for (we wanted the basket one and didn't want double basket for our needs)
In the event that we need to make more food than what would fit in the basket, we just cook one item first then sit it in the toaster oven on "keep warm" (or oven if for a larger group, which is what we did when we fed 5 adults air fryer veggies and potatoes)
