The Vitamix Explorian E310 is a significantly better multi-purpose blender than the Blendtec Classic 575. The Vitamix is much better built, and its performance producing almond butter, smoothies, and crushed ice beats the Blendtec by less time and with a smoother consistency. The Vitamix also has a speed dial, which some users may prefer, and it’s better suited for processing hot foods. However, the Blendtec is easier to clean and it comes with a Spoonula for getting the most out of your blends.
