Is there anything that a gas oven will do that a microwave/CONVECTION oven won't do, other than blow you up or singe all the hair off your arm and eyebrows? You can use either one, or both at the same time. You don't need a "stone" with convection heat as it is already equallized throughout the oven. They make great cookies and pizza. Been there, done that.
