Kirkland 18/10 SS cookware, All-Clad, or Cuisinart Professional tri-ply

I am looking to replace my 10+ year old set of Kirkland hard-anodized aluminum cookware with something new. My old set has been a steady friend, but has definitely seen better days. Also, I recently got a new Blue Star range, so I'd like to get some new pots and pans to get the max potential out of my cooking. I love to cook and hope to have this new set for a long time.

That said, I'm not the type of person to just buy the brand name if there's something else that works just as well for less money. I know All-Clad seems to be the brand to buy, but am also wondering about the two sets available at Costco: Kirkland 18/10 SS cookware and Cuisinart Professional Tri-Ply. The Cuisinart Professional looks suspiciously similar to the Cuisinart Multiclad, which seems to get good reviews on Amazon. I've also read plenty of good reviews for Tramontina Tri-Ply, but I'm trying to avoid giving my business to Wal-Mart. (I have family members in unions that would not be very excited to see me shop there.) Cost is not a huge issue, but something to consider given the price differences between All-Clad and these alternatives.
