Our Verdict

KitchenAid K400

Ninja Professional Plus Kitchen System with Auto-iQ

The KitchenAid K400 is better for most purposes than the Ninja Professional Plus Kitchen System with Auto-iQ. The KitchenAid does a better job of pureeing fibrous ingredients like kale and broccoli. It can also hot blend. On the other hand, the Ninja comes with a food processing bowl plus a pair of personal jars for single-serve smoothies, meaning you may prefer it for its accessories.
