Multifunction units tend to get the best blender reviews over Blend Away because they offer a lot more than what you normally find in basic blenders. They are more costly too, but they bring in more power and a high commercial grade. They can process frozen foods, prepare soups, turn fruits into juice, produce purees and so on. A multifunction blender has the possibility to replace a few different appliances in your kitchen. Therefore, it is not just handy, but also space efficient. Some of the more professional units come with chopping or ice crushing capabilities as well, depending on your needs.
