Ninja Mega Kitchen System [BL770, BL770AMZ, BL771] vs Vitamix A2500

The Vitamix A2500 is better than the Ninja Mega Kitchen System for most purposes. The Vitamix is better built, easier to clean, and more versatile since it can hot blend. It does a much better job of processing big batches of fibrous ingredients and makes smoother nut butter. Then again, you might prefer the Ninja if you want to use your blender for single-serve smoothies because it comes with personal jars. It also includes a food processing bowl to help with things like chopping vegetables and forming dough.
