Ninja Detect Duo Power Blender Pro vs Ninja Detect Kitchen System Power Blender

The Ninja Detect Duo Power Blender Pro and the Ninja Detect Kitchen System Power Blender are very similar, and which is better mostly depends on what accessories you want. Both blenders come with a 72oz main jar and a 24oz personal jar for single-serve, but only the Kitchen System comes with a 64oz food processor with its own blade assembly and lid. It's also a bit bigger and heavier. However, the Duo can blend a smoothie faster using the personal jar, likely because of its slightly faster max blending speed.
