Our Verdict

Ninja Blender Duo with Auto-iQ BL642

Ninja Detect Duo Power Blender Pro

The Ninja Blender Duo with Auto-iQ BL642 is better than the Ninja Detect Duo Power Blender Pro. The BL642 makes a smoother blend with fibrous ingredients, which is important for silky smoothies, and it's easier to use for thicker recipes like nut butter. It's also quieter when it's running.
