I don't like using it because of the maintenance and manual cleaning, but I do use it because of the iron rich food it makes, and the longevity of the cookware.
Also I heard Teflon is literally freaking poison for you, like one of the worst things to consume. And pots and pans always tend to flake Teflon after a while, from general use. So we got rid of everything Teflon.
I don't know how true it is but it feels good. Doing some manual labor isn't a bad thing either.
I threw my cast iron away about a year ago. Just couldn't get the hang of it, probably a me problem. Moved to a stainless steel, and my goodness, the crust I get on meats is unparalleled.
