Who is the best and worst AFL commentator?

Dennis Commetti takes first prize,because is quick,fast paced and on the ball with his fluid comments. I like Leigh Mathews and Nathan Buckeys commentaries too. Bruce McAvaney is the most annoying commentator in AFL Football. He gives the most inane comments,that are so obvious to the viewers. Robert Walls is the most boring commentator with his flat,tonal voice and negative feedback on certain players,he disapproves of .
