I have the Bullet but rarely use it as it just doesn't have the power and I got tired of stopping to scrap the food back towards the blades. I then got a Ninja which can make fluffy powdered snow from ice cubes, but still can't pulverize veggies smooth enough for green smoothies.
After 20 yrs of longing for the expensive VitaMix I finally purchased one. I love it and use it often. So easy to throw in all the fresh ingredients, flip it on for 6 mins and have hot steaming soup. The blades spin at 240 revs a second! I make my own protein bars with raw nuts, cacao nibs and dried fruit.
Like everything, it's a matter of having the right tool for getting the job done right. And in my case, with little effort.
