I wanted to upgrade my existing set and all the research indicated that AllClad was the choice. I’ve used a couple of the pots and have found cleaning to be a bear after sautéing chicken and it’s not perfectly clean after cribbing with Barkeepers Friend. 

The other pot immediately developed a rainbow stain     I followed the cleaning instructions and used vinegar but the stain persists. 

I never expected the pots to remain pristine, but two of them did not fare well after initial use. In fairness, they do cook things evenly.
