Who is the best presenter? Who is the worst presenter? Why?

I think T.J Walker is the best presenter among other of them.Eye contact is the most important thing that a presenter should have.T.J Walker have that thing.He will look to the crowd while present on something.He also have the high level of confident.He is not shy to talk in front of the audience.He manage to control himself.I also can see that T.J Walker is a ood and discipline person because he wear proper attire while present.He attract the audience by being a 'good boy' in front of others.Everybody who hear him will comfirmly satisfy in the way he's talk.I like the style that he bring in front of the audience..I want to be like him too..=]
