It's time for me to replace my 20+ year-old Revere saucepan and stock pot. I'm looking for something that's easy to maintain, and yet will last just as long as my Revere cookware. The All-Clad Copper Core seems to fit my needs; it's got the great heat distribution of copper, and easy-maintenace of stainless steel. Mauviel makes stainless steel cookware too, but according to their website the metal is not as thick as the AC Copper Core (3-ply vs 5-ply). I'll be using the cookware with a Thermador gas range cooktop, so does the thickness of the metal matter? Is the AC Copper Core worth its price, since Mauviel Stainless Steel is quite a bit cheaper? Thank you for reading folks!
