Interesting perspective, but Pichon Lalande will age faster than Leoville Las Cases. Pichon has a higher percentage of Merlot than does Las Cases, and Merlot ages faster than Cabernet.
Also, the styles are very different and Las Cases makes a darker heavier style. Far too many variables, like location, percentages into the Grand Vin, cuttings, pruning, trimmings, winemaker, chai, and more than I know.
So, I think you could say it's Finesse vs Power. They are both great wines, great scores, equal to a 1st growth; and sometimes P/L is better and sometimes LLC is better, but LLC will age longer than P/L.
I have always heard that "Patience is a Virture", but-----I don't like the wait either, but it does pay off to let a classified Bordeaux mature in your cellar.
Dr. Drab, is that you?
