I second the Brane Cantenac recommendation.
Pichon Baron is in a great place; Leoville-Poyferre was the most open of the 3 “Leovilles” last year when I tried them.
Brane-Cantenac (mentioned multiple times) and Rauzan-Segla are great Margaux options- both are in a beautiful place.
I have had a bunch and they are all (bizarrely) showing very, very well now.
This is my thought as well, but I’ve been keeping mits off my higher level bottles.
Well this is all quite fascinating, I may have to open a few and see what’s up.
