Only reason I can think of is because the All Clad handles are among the worst looking and feeling handles ever placed on a pan, but that’s of course subjective.
I just know, that unless I got an All Clad pan as a gift, I would never own a pan from that brand.
I’m sure All Clad cookware perform excellent, probably at least as good as Mauviel M’Cook, but I’m just never going to be a fan of anything All Clad.
With that said, I’m honestly not a huge fan of Mauviel M’Cook - I just happen to own 12-14 of their pans, because I was a Mauviel snob back in 2017. I’m not any more, but M’Cook still perform excellent for me, so no complaints there.
I also think one has to look at the Mauviel brand in another perspective these years.
Most professional top restaurants don’t use copper cookware anymore, and you see a lot of PLY/Clad cookware in the michellin restaurants these years.
The most popular brand of PLY/Cladded cookware I have been able to find among the many 100’s vidoes I’ve watched from top restaurants feature Mauviel M’Cook cookware in many of the kitchens and that’s a pretty good sign, that Mauviel M’Cook cookware is solid performing cookware.
