The Beatles, as the sum of their parts, were the best band ever. They just were/are. Ray Davies was an OK songwriter, as was Pete Townshend. Nothing more than that
I always think of bands/artists in terms of a pyramid. Most bands are at the bottom, and the higher you go the fewer bands there are in each tier. Finally, at the top, you have The Beatles on their own. Simple as that, really
