Polyamourous Cookware Lovin
There are differences between the brand names of the D-T-D cookware. Some are heavier weight than others, edge or lip of the pans, lids are different shapes and vented/non-vented, etc. It's best to shop around at Goodwill, estate sales and the like to find pieces or entire sets and try them all on for size. Different shapes, handles, weights all play into the cookware, each cook prefers something different for reasons all their own. My mother bought a set of Wonder Ware (Regal) along with a set of Cutco knives when she married in '65 and still has them all. Several warranty replacements of lid knobs and sharpening/replacements of knives is all that she's needed. That said, she's likely to fight for her Revere 1-1/2 qt. saucepan and lid among a few other oddball pieces that she compliments the WonderWare with.
I have various pieces of Queen (Amway) and Seal-O-Matic that I enjoy using right along side my All-Clad and Kirkland Signature 5 ply as well. I don't think I'll ever let my 4 quart All-Clad saucepan or non-stick skillet get too far away and I'm growing to love my All-Clad 2 quart "everyday" pan just as much.
