The decision in plain terms
Choose 3.7 Quart Digital Air Fryer if you want the smaller advertised capacity. Choose 5.8 Quart Digital Air Fryer if the larger advertised capacity fits your batch plan.
The key documented difference is advertised capacity. That difference does not establish a proportionate change in usable cooking area, portions or cooking speed. There is no hands-on performance winner or live-price winner in this comparison.
