Personal blender vs. full size blender: which is better for smoothies?

Personal blenders (like the Nutribullet style with single serve cups) are better if you make one smoothie at a time and want easy cleanup. Full size blenders are better if you batch prep, make smoothies for a family, or also use the blender for soups, sauces, and other recipes. Personal blenders blend directly in the cup you drink from, saving cleanup time. Full size blenders offer more power and capacity but require washing a larger pitcher.
