Who’s the best? It can only be one. The best is enemy of the rest. Of the good. Of the different. There’s always one better. A later one learns from, and improves on, an earlier one. The game evolves and is refined. Something new is added that overshadows the old. Beethoven learned from Hayden. Michael Jordan is 6’6’’ tall. So is Julius Irving. But Michael learned from Julius. Who can judge which butterfly is the best?
