Demeyere vs All Clad vs Mauviel

So I have about $1,000 - $1,600 to spend. I am looking at new cookware and am deciding between the following in the title. I am looking for what I feel is the "Best cookware" I have had Calphalon and Analon Copper Core but I am planning to steer away from non stick and go stainless steel. All you chefs and avid cookers what do you think of my breakdown? I am really feeling the Demeyere, but each line has so many differences I cant decide. I most likely will buy them from Bed Bath beyond with my gift cards.

All Clad D5 or the Copper Core

Demeyere - John Pawson or Atlantis-I saw industry5 but I am not sure of it

Mauviel M'heritage - I will be honest to me it just looks good, I know it's quality, they all seem to have copper and the stainless steel to surface to cook on, coupled with many handle types.

Would love to hear the discussion going here

FYI: I want it to work on Gas / induction / electric. Right now I use gas, I always hand wash as well so dishwashers don't make sense.
