There’s also a potential health argument against cooking with Teflon pans to begin with, but people do and those people shouldn’t be using metal if they want their pans to stay non-stick for any reasonable length of time.
I switched to carbon steel as a daily driver two years ago and it is is trivialy non-stick with a little maintenance. The non-stick properties are infinitely refresha le, unlike "non-stick" pans.
I also have cast iron and stainless pans for other uses.
Unfortunately try as we might to get people to switch, the fact is that undamaged Teflon is more non-stick than anything else and most people don’t want to put the effort into seasoning their pans.
Teflon is popular, and Teflon owners could do with utensils that don’t destroy their pans or give them cancer.
