Our Verdict

Ninja Mega Kitchen System [BL770, BL770AMZ, BL771]

Ninja DUO

The Ninja Mega Kitchen System and the Ninja DUO perform fairly similarly. The DUO makes a smoother blend with fibrous ingredients, which makes it better for smoothies. Its blade design makes it easier to clean. On the other hand, the Kitchen System comes with a food processing bowl and an additional blade assembly for forming dough.
