I already own some of their stoneware pieces but decided to invest in this heavy enameled cast iron au gratin pan. I've used it on the stovetop (which I cannot do with the stoneware) and also in the oven. It's also safe for the broiler and the bbq grill. The heft and material create a wonderful fond which is difficult to burn (I find it's much easier to burn things in a thin pan.) It needs a short soak before cleaning up easily. I love roasting a whole chicken in it and then using the caramelization on the bottom to make a wonderful sauce on the stovetop (deglaze with wine, broth or even just water.) The versatility of it makes me favor it over their stoneware.
