Well shucks, Cyndi, I don't think anyone has one
Judging from the reviews on Amazon, I think they come in pretty evenly. However, I've heard that one might be better for one thing while the other might be better at others. So it may depend on what you plan to do with it. I've read that the Vitamix makes smoother smoothies. Of course I can't vouch for it.
I have a Breville Ikon which I love and wouldn't part with, but has mixed reviews on Amazon. I tend to pull out my kitchenaid stick blender for smoothies. Not because it's any better, but simply because it's easier to clean and I'm lazy
Congrats on your present to yourself! Either one will be a treat
