You need stainless for acidic foods. We have both types of frying pans. The problem with Teflon as I understand it is that it breaks down to PFAS at temperatures that are easy to reach in a frying pan. It might be that Teflon other things are better (like a stand-alone grill thing), but I just try to avoid it.
