I'm probably repeating a post I made - perhaps in the aforementioned thread, but having two mixers side-by-side on my countertop, the KitchenAid is not my favorite for pizza dough.
Long ago my wife wanted a mixer with all the bells and whistles for her birthday (i.e. a KitchenAid). Me, being the frugal SOB that I am, shopped around and found a Kenmore with all the same attachment possibilities, more power, at about half the price. I think she might've been a little disappointed, but (little as I might've expected at the time) I turned out to be the mixer user in the house. And I was pretty happy with the Kenmore.
Then some years passed and we remodeled our kitchen - with a lot of black and stainless steel. We had to have the stylish KitchenAid. The Kenmore went into a cupboard. But some time later, the cupboard it was in got moved and I rescued it and tried it again.
It did indeed have more power and didn't walk all over the countertop during serious kneading. But what, oddly enough, I came to love was the plastic bowl. Drying dough remnants will cling to stainless steel. But in the plastic Kenmore bowl, you can just let it dry completely and it will then flake off effortlessly with the slightest flexing of the bowl.
Unfortunately this characteristic is not good for some other things you might what to do with the mixer. Like whipping egg whites. There, the stainless bowl is better as doesn't retain fats from previous uses that could interfere with this exacting process.
And, well, this is how I wound up with two mixers side-by-side.
