After researching hundreds of products, we have found that stainless steel dinner sets are the best in terms of durability, sturdiness, usability, weight, and food safety. Opalware sets are also very good. They are less durable than stainless steel but have a better visual appearance and more attractive. Opal-made dinnerware is a very good choice as gifts. Apart from these two materials, we also recommend porcelain and melamine dinner sets.
