Our Verdict

KitchenAid K400

Ninja Foodi Power Blender Ultimate System

The KitchenAid K400 and the Ninja Foodi Power Blender Ultimate System have different strengths. The KitchenAid K400 makes a smoother blend with big batches of fibrous ingredients, and it can hot blend, so it's better for multiple servings of smoothies and soups. On the other hand, the Ninja comes with lots of extra accessories, including personal jars for smoothies and a 'Smoothie Maker Bowl' that makes it easy to make thick mixtures like nut butter. There are also extra blades included for tasks like forming dough and slicing vegetables.
