We bought a BlendTec 3 or 4 years ago at Costco. We had been doing a lot of research, watching a lot of
youtube comparisons etc. It didn't seem like there was a clear winner, it really seemed to come down to personal preference. For me, I was leaning towards the BlendTec because it fits under my counter and I liked the square jar better. Then there was a VitaMix lady at Costco- she was a total snot and a royal witch. I didn't like the face she put on the product, so it sealed the deal for the BlendTec. My neighbor has a Vitamix, we've swapped machines before to test drive the other and both of us prefer the one we bought. LOL Nothing wrong with either, just preferences.
