Both the KitchenAid Architect and the Sub-Zero refrigerators were reviewed by Good Housekeeping and given B grades. However, the KitchenAid Architect is thousands of dollars cheaper than the Sub-Zero, as of 2015.
The pros of the KitchenAid Architect include interior LED lights, adjustable glass shelves and a built-in air filter. The doors of this refrigerator are large enough to hold gallon bottles, and the drawers feature temperature controls. The cons of the Kitchen Aid Architect include the meat drawer is not colder than the rest of the refrigerator and hard-to-use controls. There is also a large ice maker in the Architect, but it takes up a lot of room.
The pros of the Sub-Zero include even freezer temperatures and easy to use and read digital controls. However, during the review process with Good Housekeeping, the Sub-Zero failed to keep temperatures even in the refrigerator, and the shelves are not adjustable. This refrigerator is also not ENERGY STAR rated, which may be a concern to some consumers. The Sub-Zero has a smaller capacity than most other refrigerators, and it does not have some commonly included features, such as an ice maker, water dispenser and humidity control. It is, however, very professional looking and performs exceptionally well.
