But as good as it is, it will never be as truly non-stick as a good teflon pan.

Don't get me wrong, I use and love both my cast iron and a few old All Clad stainless with copper cores. Teflon will never sear as well, never give you the ultimate maillard you're looking for.

But you can crack an egg into a teflon pan without oil and slide it out without leaving a trace.
