who is the best presenter?

From the video I think The best presenter is Doug Jeffry's second is Ed Tate, Third is Randy Paunsch, Tj walker fourth, Dick hardt presentation is bored but he is better presenter than the Microsoft dude which is the worst presenter. I choose Doug Jeffry's as the best presenter because he knows how to attract the audience with his jokes. He also have a confidence to speak in public . Microsoft dude is the worst presenter, he seems to be unprepared and show he is lack of confidence to speak. I think Dick Hardt is a good presenter if he talks directly using lesser slide because he has the confidence to give a public speech but his slide a repeated. Ed Tate,Randy Paunsch and Tj Walker I consider to be equal, they got the confidence obviously because they are professional speaker.
