I have no idea, all I do know is that between them they made some damn good music.
Best musician would probably have to he Paul McCartney. He can play numerous instruments.
McCartney the best all around, innovative too.
Paul and George were the most talented. However, I believe Paul has mastered the most instruments, and can compose music and write lyrics better.
Sir George Martin---without his production and musical knowledge the best of their music wouldn't exist
George Harrison. Years ago I woud say equal.
All of them. The most prolific was Ringo, next Paul, and then Geore and John. But the best is the band, which is a unity.
