Lafitte is the only one I've come close too (I smelled the dregs of an empty bottle). It had the most dilightful aroma of any wine I've been near. Now I admit I am throwing off the results of this poll which doesn't include HB.
I've had the following:
'67 Haut Brion - $10 (1977)
'67 Lafite - $10 (1977)
After drinking the above, my wife and I fell in love with the Lafite, so we purchased a case of the '75 Lafite (year of our wedding) - $30 (1978) and have opened 1 bottle every 5 years - great stuff. As my wife passed away in '04, the last bottle I opened was shared with my sons, in her memory. They all were amazed by the wine.
That's why one should refer to "left bank Premiers Grand Crus Classés reds", because one always tends to forget that to the four reds from 1855 come one "Premier Cru Supérieur" (Yquem) and 9 other "1855 Premiers Grands Crus Classés" in white (today 11).
