I am planning to buy a KitchenAid mixer for my wife as a birthday present. However, there are multiple models and I am not sure which one to pick. My wife will be using the mixer for making cookies, cake, pizza dough, and possibly bread.
One of the main differences between the models is the wattage, with some models having 325 watts while others having 575 watts. How important is the increase in wattage for my wife's uses?
Another difference that I found is that some model has a burnished metal dough hook while the other model has a nylon covered dough hook. Would this be a big advantage/disadvantage for either models?
Thanks.
