You are looking at 2 very different type of cookers. The Kamado's, including the BGE, are very versatile and are set it and forget it type cookers. In fact, the less you open them during the cook, the better. The offset will have similar type of time requirements that you had with the Banderas. But, the flavor and style of cooking is more what you are used to.
