Our recommendation
Choose the Ninja AF101 if you cook for one to three people and want the most proven 4-quart air fryer with the smallest sensible footprint. Choose the Cosori Pro II if you need more room: its 5.8-quart basket serves families at a value price tier. The real decision is household size, not brand loyalty.
Capacity
The headline difference. The AF101's 4-quart basket suits two to three people; the Cosori's 5.8 quarts serves four or more without batch cooking. Bigger is only better if you actually fill it.
Functions
The AF101 keeps it simple with 4-in-1 functions covering air fry, roast, reheat, and dehydrate. The Cosori Pro II offers a broader function set for its class. Neither has the rotisserie of the larger Instant Vortex Plus.
Footprint and value
The Ninja is smaller on the counter and carries the category's longest track record. The Cosori gives you roughly 45 percent more capacity at a value-oriented price tier, making it the better capacity-per-dollar deal if you have the space.
Choose Ninja AF101 if…
- You cook for one to three people
- Counter space is limited
- You want the most proven track record in the category
Choose Cosori Pro II if…

Questions, answered
Which crisps better, Ninja or Cosori?
Both crisp well when not overcrowded. Smaller baskets like the Ninja's can actually crisp slightly more evenly on small loads because the hot air has less space to fill; the Cosori wins on big loads because food is not piled up.
Is the Cosori harder to clean than the Ninja?
Not meaningfully. Both use nonstick dishwasher-safe baskets. The larger Cosori basket is simply bigger to handle, which matters more in small sinks than in dishwashers.
