I’d posit that your well-loved cast iron looks even better than new. For me, moving off nonstick pans was about sustainability (and money waste, who wants to buy a 2 year subscription to cooking?), but I can’t get over how beautiful some cookware gets just from being used. The patinas on cast iron/carbon steel pans reflect the dedication of their owners to a craft, which I’ll take any day over a colorful pan whose surface flakes just from looking at it.
