What is the difference between All-clad versus Multi-clad cookware?

All-Clad is a specific brand known for its high-quality cookware, typically featuring a stainless steel exterior with a core of aluminum or copper for enhanced heat conductivity. Multi-clad cookware, on the other hand, refers to a construction method where layers of different metals are bonded together, often found in various brands, including All-Clad. The key distinction lies in brand reputation and specific construction techniques, with All-Clad often being considered top-tier due to its durability and performance.
