Max 15-in-1 SmartLid 7.5L or Air Frier Dual Zone Max?

My wife and I are looking at getting an air frier, and it's pretty common knowledge that Ninja Foodi are the ones to go for...But, there are so many options we are having difficulty deciding which one is best for us. The primary function we are after is air frying, so we're originally looking at the Air Frier Dual Zone Max, but price wise it is pretty much exactly the same price as the Max 15-in-1 SmartLid cooker.

So, my questions are:

• is the air frying capabilities significantly better in the dedicated air frier than in the 15-in-1?
• can you air fry multiple ingredients at the same time in the 15-in-1, for example chicken and fries, like you can with the dual zone airfrier?
• do, in your experience, the extra features of the 15-in-1 outweigh the inconveniences of it (whatever you may perceive them to be)?
• People who have both/either: is there anything you don't like about the product?
• any good links to videos/articles comparing the two?

Any help would be greatly appreciated!
