I think it all depends
If you know food, know your way around a kitchen, and I know it's all about this oven. But the appliance won't make you a better cook. I know people with homes that put in these $50,000 kitchen and their refridgerators are filled with take out boxes and they only use the top rack of their dishwashers for glasses and coffee mugs. The Bottom rack only gets used on holidays when they have a caterer come in. My $299.00 Kenmore Range can cook as good as a $5,000 Range. Even though I'm a graduate of The Culinary Institute of America, , It's all how you handle the heat and get to know your range or oven for this matter.
