The same build
Both are tri-ply: stainless steel inside and out around an aluminum core, clad all the way up the sides. Both sets are six pots and pans and four lids, both work on every stove including induction, and neither has a coating to wear off.
What each set holds
Both have 8- and 10-inch fry pans and a 3-quart sauté pan. ZWILLING’s saucepans are 1 and 2 quarts and its big pot is a 6-quart Dutch oven; All-Clad’s saucepans are 2 and 3 quarts and its big pot an 8-quart stockpot, the one that takes a pound of pasta with room to spare. ZWILLING’s lids are tempered glass, All-Clad’s stainless steel.
Oven, broiler and care
All-Clad rates D3 to 600°F in the oven and under the broiler. ZWILLING rates Spirit to 500°F and doesn’t mention the broiler. The care rules run the other way: ZWILLING says Spirit is dishwasher safe and metal utensil safe, while All-Clad says D3 is hand wash only and doesn’t say either way about metal tools.
Weight, origin and warranty
ZWILLING lists Spirit at 19.84 lb for the set and All-Clad lists D3 at 25.9 lb. Spirit is made in Vietnam; D3 in the USA with global components. ZWILLING calls its warranty lifetime and All-Clad its warranty limited lifetime.
Which one to buy
Choose ZWILLING Spirit if the dishwasher matters, for a lighter set and a Dutch oven. Choose All-Clad D3 for the hotter oven and the broiler, bigger saucepans and an 8-quart stockpot, made in the USA.
