The decision in plain terms
Choose Vortex Plus 6QT ClearCook and OdorErase if you want one undivided cooking basket. Choose Vortex Plus Dual 8QT ClearCook 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.
