I think Ringo should be credited with keeping them together. I've heard that Pete Best's good looks overshadowed John, Paul, and George. If he had stayed, that may have caused group instability. Plus, with Ringo, there was one less creative prima donna in the group.
And Ringo was/is genuinely funny. His presence contributed quite a bit to the Beatles humor and charm, particularly during the famous first trip to America.
