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.

GAF652: model-specific notes and limitations
The official US shop confirms the SKU and capacity; optional preheat and turn-food reminders are documented. We list only the cooking modes the manufacturer names individually. The two unlabelled size figures it publishes are not enough for a fit check. The shop showed Sold Out when we checked. The US manual asks for at least 4 inches above and around all sides; how far the drawer opens is not quantified.
