Sorry to avoid your specific question, but just a little comment that I’ve found the enamel/ceramic coated cookware to hold up extremely well and work well for me.
But I cook my eggs on a nonstick griddle I have - cheap from Walmart, like $15.
In general, if your eggs are sticking, you are not letting the pan heat up before you cook (typically non–nonstick metal pans/skillets need this), or you’re just not using enough fat/oil. It doesn’t take a whole lot, but you do need some.
