Cast iron is durable. It heats slowly but once hot it retains heat well and evenly. The advantage of an enameled cast iron is that it doesn't react with acidic ingredients like vinegar. The disadvantage of an enameled cast iron is that it does make it even heavier and often the enamel can chip easily if not taken care of. Enameled is easier to clean than uncoated cast iron. An uncoated cast-iron needs to be seasoned while an enameled does not. You just wash and put it away like any other pan.
