After looking at this blender question, I had a follow-up question.
I've seen both square and round containers/lids for blenders. Is either better?
I tend to see square blenders at smoothie shops - leading me to assume square ones are better. By better I mean, you don't have to do as much scraping and maybe they have more settings and automated features. I see mostly round blenders in your typical kitchen appliance aisle at your typical big box store.
