Speed oven vs air fryer oven

So a speed oven basically is a microwave convection unit that utilizes both functions at the same or intermittently to get things done with the speed of a microwave but the browning nature of an electric element.  An air fry feature found in many regular stoves today is like convection on steroids. It is a higher-speed fan and computer-controlled algorithm that will crisp items thoroughly with the additional use of perforated trays so the food is cooked from all sides. Air fry is an option found in many new ovens today and works great. So speed oven is good for micro replacement as most speed ovens function as a microwave as well yet most air fry features are just an added option to a stove. Two different appliances.  Not to totally confuse you but this unit from GE is almost like an all-in-one as their Advantium technology does give results as an air fryer would. GE / MONOGRAM Oven
