Our Verdict

Blendtec Classic 575

Ninja Smart Screen

The Blendtec Classic 575 is a better blender than the Ninja Smart Screen for most uses. It makes a smoother blend with fibrous ingredients, it's easier to clean by hand, and it has a wider range of speed settings. However, the Ninja is much better for recipes like nut butter or hummus, which is a weakness of the Blendtec.
