LOL at hiding behind the “some folks attribute these notes”. The wines can be bretty as hell. Own it, baby! There’s nothing wrong with loving brett, to each their own.
Although I love several vintages of Ducru it is not my fav. super-second … and the disapointments between 1985 and 1990 have drawn my nerves …
On the other hand I simply cannot say which is THE best/preferred … depends on age/vintages … and I also would not limit it to the 2nd growths from left bank at all, not even to all classified growths (incl. e.g. Pontet-Canet, Grand-Puy-Lacoste, Palmer …), but equally incl. LMHB, recently Pape-Clement, but also Pomerols like Trotanoy, Conseillante, L´Evangile, Vieux-Ch-Certan … (I would consider Petrus and Lafleur as true 1st growth).
And if we are talking about St.Emilion … which classification ?
… and typically Palmer, and typically Pichon Baron, and typically Cos, and typically Montrose, and typically Lynch Bages … and typically many others … even typically Mouton …
(typically wine …)
