Ninja Mega Kitchen System [BL770, BL770AMZ, BL771] vs Detect Kitchen System TB401

The Ninja Mega Kitchen System and the Ninja Detect Kitchen System TB401 are both full-size blenders that come with 72-ounce main jars, at least one personal jar, and a separate 64-ounce food processor. They perform quite similarly, so which is better comes down to preference. The Detect is a newer model with an LED display, so you can see how long is left in a blending cycle. It has more options for automatic blending, including a 'BlendSense' feature that's meant to detect what you're blending and adjust the blender's performance. It's not quite as loud. On the other hand, the Mega feels sturdier. It makes a smoother blend with fibrous ingredients in its main jar, although it's not a huge difference.
