I have owned a Vita-Mix Total Nutrition Center for about 11 years now. I have used the Blendtec before also in commercial kitchens etc. I would definatley choose the Vita-Mix over the Blendtec mainly becuase of the tamper design which is essential when making large ammounts of juice or peanut butter etc. The Blendtec also has a computer system which means there are many more parts to break down. The Vita Mix will last much longer and is far superior for making total juice with seeds, peels etc. and makes much smoother nut butters. Vita Mix is Best by far!
