Ninja Detect Kitchen System TB401 vs Vitamix Alta Pro

While the Vitamix Alta Pro and the Ninja Detect Kitchen System TB401 are both full-sized blenders, they meet very different needs. Get the Ninja if you're looking for an accessory and feature-rich option. It comes with a 72-ounce main jar, a 24-ounce personal jar, and a 64-ounce food processor bowl, whereas the Vitamix only has a 64-ounce jar. This makes the Ninja the better choice if you like to blend single-serving smoothies to take on the go. The Ninja also comes with a BlendSense feature that automatically selects a blending program based on the contents of the jar. When blending large batches, however, the Alta Pro performs significantly better. Finally, if you want to use your blender to make soups, the Alta Pro has the clear edge because the TB401 can’t hot blend.
