I am trying to decide between two 11" copper saute pans and could really use some advice, since it is a big investment for me. Mauviel Cuprinox is 2mm thick. I am getting the pan with 2 helper handles instead of the long one because of back problems. e-dehillerin has the same pan at 2.5 mm thick. Cost is a little less for the E-deh if ordered from France. Could they both be made by the same company? I have read posts saying that the difference in the copper thickness is negligible. Both come with lids and are stainless lined. Mauviel has ss handles and the E-Deh. is iron or brass. Any glaring problems or differences? I have an electric (not induction) range. Please advise.
