Anything that is made by Kitchen Aid is great! To me, yes the kitchen aid oven is the best. They have baking, toast, broil, rotissere, and warm. Kitchen aid is the way to go with any appliances.
If you need a new oven and you are looking for the very best than I would recommend putting commercial quality ovens and appliances in your kitchen, KitchenAid does make high quality appliances, and I would recommend them if you do not want to spend the money on commercial ovens.
