Breville ovens are smarter. I bought the original 9 function Smart Oven in 2010 and loved it the first time I used it. Soon my full-sized oven was starting to get resentful, and for good reason. The Breville preheated faster, kept a more even temperature, and offered more functions than its full-sized cousin.
Another thing I really love about these ovens is the timer. It counts down and turns the oven off when the time is reached. Set it for and hour and after an hour the oven turns off. This feature alone has saved many meals at our house.
