Our Verdict
Ninja Blender Duo with Auto-iQ BL642
Blendtec Designer 725
The Blendtec Designer 725 is better than the Ninja Blender Duo with Auto-iQ BL642 for most purposes. The Blendtec is sturdier, easier to clean, and makes a smoother blend with fibrous ingredients like leafy greens and fruit in its main jar. On the other hand, it only comes with one jar for single-serves, while the Ninja comes with at least two. The Ninja is also much better for making thicker blends like nut butter or hummus.
