I cook with both. I have a Weber propane grill for handling all the basic stuff like steaks, burgers, pork, fish, and chicken. But if I am doing a roast, prime rib, or BBQ or anything else that requires low temperatures and slow cooking then I use my Primo ceramic cooker. With the Primo, you can not use briquettes or lighter fluid,you use real charcoal wood, or mesquite. But even with this limited fuel source, you have excellent temperature control. I can even bake a cake or a pizza inside.
