It is said that the universal air fryer is the hurricane version of the oven. Why do you need to ask this question? Air fryers have more possibilities than ovens. I think the air fryer is easier to use, and there is no need to put oil and smoke. Very cost-effective. When I got married, I knew there was an oven and didn't buy it. Now we are left out in the cold. My mother-in-law and I used a lot of delicious food in the air fryer! Haha, this is what my mother-in-law just made. It is delicious.
