My MH came from the factory with a cooktop and a deep drawer underneath it, and a convection microwave for oven cooking. The only issue I have is virtually all of the cooktops are three burner. Yes, I am single, so I don't do a lot of cooking, but even my mother at home cooking for the whole family was hard pressed to use three burners.
Personally I don't want a lot of cooking going on in the MH, smells and grease splatter, smoke, etc that cannot be removed.
Of course it all depends on what you are doing and your lifestyle.
