Cast iron takes longer to heat up but maintains it heat much longer, I have a griddle that when hot enough to do pancakes, it will will still burn your hands after 45 minutes of heat being removed.

Cast iron when seasoned properly can be relatively maintance free for a while.

Cast iron can also be used on many surfaces then conventional pots and pans, in the image you see me cooking over a campfire. Cast iron is also heavy which means you don't need to hold it when you turn something. Oh and don't forget the fact that cast Iron can last longer then 200 years.

I personally like cast iron a lot.
