I have only used the new oven for a couple of weeks. We are getting used to the high and low feature of the broil function. We have over cooked a couple of steaks. It will take some experimenting. It has baked cakes evenly. I love the bright light in the ovens to be able to see the food cooking. I wish you could turn the light on in each oven separately as it seems a shame to shorten the life of a light bulb that you do not need in the oven that is not being used. It seems that it takes a long time to preheat the ovens, but I have not actually timed it. My husband remarked that he, also, thought it took a long time to preheat. Overall, I am happy with the double wall oven.
