Both air fryers get good results, but they are a little different. The oven air fryer takes longer because even though it uses a fan to circulate the hot air like a basket style air fryer does, the fan moves slower. The basket style is the best one to use for broccoli, not just because of the quicker cook time, but because the basket enables more even cooking as the air reaches the undersides of the broccoli as well as the tops and sides.
