There's no difference in glass or porcelain. They are all porcelain lined, just been called glass for many years. Must be 2 different brands or they are calling one glass & one porcelain to make you think you're getting a better product & they get to stick a little extra cash in their pocket. Even if there was a difference, it's a liner to keep water from touching the steel & rusting or corroding the tank so it shouldn't matter as long as water doesn't touch the steel.
