Frankly, Jacko doesn't even come close in that category. Sure, he was a good dancer, but that was about it. He sang lousy songs, and had an average voice.
The best entertainer of all time was Al Jolson. ...and then probably Louis Armstrong. And of course Elvis Presley is right up there. And Sinatra. THOSE were entertainers.
And as for dancers...
His only good song in my opinion was Billy Jean.
