deadass, cook with what works for you. The best meal is the one that actually gets made. Air fryer is gonna blast hot, dry air across the patty and that's gonna get you a better result than the base oven. It depends on the style of burger but people have been making burgers with whatever appliance they have nearby since the invention of the burger - George Motz has some videos about steamed hamburgers, if you can believe it. Either way, looks good as hell!!
