The decision in plain terms
Choose 3000 Series Airfryer 6.5 Qt if you want one undivided cooking basket. Choose 5000 Series Dual-Basket Airfryer with Steam if two baskets suit foods with separate settings.
The key tradeoff is shared cooking area versus separate zones. A total quart figure does not tell you which large items fit into each drawer. 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.

NA330/00: model-specific notes and limitations
USA catalog confirms exact non-R0 identity, quart-labelled capacity, cooking window and RapidAir Plus. Refurbished R0 variants and cosmetic NA331 variant are not duplicated. Full mode list and exact US electrical values await manual.
NA555/00: model-specific notes and limitations
Manufacturer labels total capacity 9.6 qt and drawers 6.3 plus 3.2 qt; rounded drawer figures sum to 9.5, not 9.6. Do not silently reconcile. Steam-clean function is documented for the large basket; electrical and dimension records await US verification. 2026-10-03: the official US page links a North America NA55x guide asking for 20 cm (converted exactly) at the back, both sides and above, and not beneath cupboards; the guide names the NA55x series rather than NA555/00.
