The Ninja DUO is a better overall blender than the NutriBullet PRO 1000. The Ninja is a full-size blender that comes with a 20-oz personal jar, so it’s a better choice for larger batches. It’s better-built, and it comes with more features, including preset modes, a pulse mode, a timer, and a juicer attachment. The Ninja can make smooth, spreadable almond butter and a more drinkable smoothie, and it crushes ice in less time. That said, the personal-size NutriBullet is easier to hand wash.
