While I agree with the advice, and all I use are steel and cast iron, I think you need a big disclaimer on "they don't stick." To a new user coming from Teflon, they absolutely stick.

It takes a combination of seasoning and temp setting to get something approaching nonstick, but if we're being honest, it's still not quite as slippery as Teflon. For most people though, I think it gets good enough.
