I owned a 27" kitchenaid wall oven and replaced it with the 27" Cafe Platinum. The Kitchenaid was 1" wider and taller than the Cafe". I found that the inside surface is not at all forgiving when it comes to spills as my other oven, very difficult to clean up.  The Cafe oven has oven is a very attractive clean looking oven. The touch screen is very attractive and so far the temperature very accurate. I cook with a thermometer.
