Our Verdict

Oster Pro 1200

Ninja Blender Duo with Auto-iQ BL642

The Ninja Blender Duo with Auto-iQ BL642 and the Oster Pro 1200 have different strengths. The Ninja is sturdier and quieter and comes with three personal jars for single-serves instead of one. However, the Oster does a better job of processing big batches of fibrous ingredients in its main jar. It can also hot blend, making it better for big batches of smoothies or pureed soup. It's easier to clean by hand, and its main jar is made of glass, which is less prone to scratching and discoloration.
