It’s not super clear what you’re getting at here. The choice isn’t teflon or oil. Everyone uses fat to sear food in a pan, whether or not it’s a nonstick pan. Cooking with a high-smoke-point oil which is low in saturated fat, such as avocado oil, with stainless steel, is strictly better than cooking with teflon pans by every measurable health metric.
