Imagine the air fryer sitting on a counter with a depth of 2x the frye depth. If the door is single hinge (on side or bottom), then you cannot have anything sitting in anywhere in front of the fryer when you open the door (it will block the door).. with French doors, you can. With a full size oven in a very narrow kitchen, French doors would be similarly preferable.
