Why do things taste better when cooked in a cast iron skillet?

So I’m just wondering if there is reason things taste better in a cast iron skillet? A steak for example, I will cook a steak only on the grill most of the time but if it’s bad weather outside I will cook indoors only using an iron skillet. Is there some scientific explanation as to why the use of one is better than you average metal skillet? Maybe something to do with distribution of heat?
