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.

What could change your choice
Measure the food footprint you need, inspect the manual's clearance instructions and confirm exact-model accessories. Unknown dimensions and coating chemistry are not equivalent to zero or an adverse finding. Current price, stock and personal budget can reverse a specification-based preference.
