Gas Burner vs Stone Accessory
Fuel type

It sits inside the oven. You must use your oven’s existing heat source. The stone just holds the heat. The burner gives you a new power source. This is a clear win for the Ooni accessory if you want to switch fuels. The stone is passive. It relies entirely on the oven you already own. One adds power; the other just sits there.
Temperature control
The Ooni burner includes a heat control dial. You can adjust the flame to cook at lower temperatures. It supports low and slow cooking for meats or delicate pizzas. The BMMXBI stone has no controls.
