I've cooked on BGE's for 15+ years, I have a large and a small in my arsenal of grills and smokers. In those days, there were only a couple of brands to choose from, and now there quite a few.
I don't think you could go wrong with any ceramic cooker, you just need to compare features (which will be similar), warranty, factory accessories, and after-market accessories, price and availability. I can tell you ceramic grills are very versatile... griling, smoking/barbecuing, roasting, baking, wokking (if that is a word for cooking on a wok?). I also use some vintage cast iron griddles, pans and even a camp oven on occasion. Baking essentially means that anything you bake in your oven is possible, pizza, biscuits, cornbread, lasagna, enchiladas, Big Green Eggplant parm, mac and cheese, baked beans etc., etc. I've never baked sweets because they need the cleanest burning fires. I have done all night cooks when the temp is -25° actual, and I've done lo-n-slo cooks where one load of charcoal lasted 18 to 20 hours.
I'd be happy to field some more specific questions related to cooking and I may be able to answer general questions about brands other than BGE's.
