With respect ... the best was Wagner made in Sidney OH. But they've been out of business for decades. I still see them at antique shops.
All mine are Wagners. 2 skillets #3 #8 and a stew pot with a handle and cover.
The stew pot sits on the wood stove all winter and is home to whole chickens,deer and lamb through out the winter.
Every now and then I let the skillets sit on top for days and I think that helps them retain the superb cooking results they provide.
Also, many people don’t realize iron cookware provides an excellent source of iron in our bodies.
My Pappy us’tah say folks became deficient when we went to aluminum and other junk to cook with
Wagner? Nah, they were a Johnny come lately. In March 1957, McGraw-Edison of Chicago acquired Griswold Manufacturing. Later that year the Griswold brand and housewares division were sold to the Wagner Manufacturing Company of Sidney, Ohio.
