The decision in plain terms
Choose Dual Blaze 6.8-Quart Smart if you want one undivided cooking basket. Choose 9.0-Quart Dual Basket 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.

CAF-P583S-KUS: model-specific notes and limitations
A single basket with upper and lower heating elements; VeSync app control is documented. COSORI reports exterior dimensions of 11.7 × 12.9 × 13.8 in without labelling which figure is the width or the depth. The US manual asks for 5 inches behind and above plus room to remove the basket. Side clearance is not quantified, so the full operating clearance is unknown.

The manual requires at least 5 inches behind and above plus room to remove the baskets; side clearance and how far the drawers open remain unknown.
