I don't have either but I can say that I've never heard anyone have something good to say about Dacor. I'd avoid it just based on the unanimity of people's opinions. That's pretty rare.

Also, I was actually kind of excited about the android-powered Discovery appliances. Then I kicked the tires and found that it is absolute garbage. It's running on an old outdated version of the Android OS (I don't remember which) and it allows you to install whatever you want from the Play store with no contingency plans for crashes.

Android is far from perfectly stable. It will hand and it will crash, especially if you install apps that increase the instability of your device. These appliances have no contingency plans for crashing. If the Android tablet crashes you're going to burn your food and possibly cause a fire.

Also the recipe database was extremely limited. There was one or two options for each kind of food (chicken, fish, etc.) which is kind of ridiculous. It's the clunkiest piece of technology I've seen on a kitchen appliance. Total garbage.

You will get more responses in the Appliance Forum. In general, no one I know has had any luck with Dacor.

Neither. If you don't want open burners, then the sealed burner Wolf is your best bet.
