nonstick cookware has made a bad name for itself in being unsafe due to the harmful PFCs (perfluorocarbons) you ingest after cooking on it. that being said, i don't recommend frying an egg on even the most perfectly seasoned cast iron skillet as it literally becomes one with the pan (at least for me).
belgian-based greenpan cookware is nonstick, PTFE-free (sans teflon), and the recycled aluminum base emits zero toxic fumes under high heat. why didn't we make nonstick pans like that in the first place?
