I am buying tis new model Ninja Auto IQ.. I have a Ninja that is about 6-7 years old. It is the best machine i ever used. It has done everything. Make dough. smoothies, ice cones, 
batters,  chopped nuts anything you can think of. It's still running strong. I just felt like an ugrade. I have kitchen aid stand mixer that does nothing and costs more.. i will let you know about the new one
