This is my opinion too - you might be able to convince me to roast it in the air fryer, but I'm more likely to cook it in the microwave and then just do a minute in the air fryer to crisp it up (our oven's broiler/grill is broken, otherwise I'd crisp it up under that)

Unless I'm making jacket potatoes for more than 5 people (in which case a big baking tray in the oven makes sense) the microwave is just so fool proof for a cooked spud.
