They're good, but not sure if I would, personally, call them 'god-tier'.
But then again, every one has their personal preferences. It would be wanton of me to say anyone is 'wrong' (unless we're talking about square-toed shoes) when it comes to personal preferences.
I have some Mazarin, Gamarelli, and Bresciani socks. Having tried these, as well as Pantharellas and Corgis, I've found the Mazarin/Gamarelli/Bresciani ones to be better. In my case, I guess, 'god-tier'.
