The decision in plain terms
Choose 6-Quart Digital Air Fryer if you want the smaller advertised capacity. Choose 7-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.
