Which Authors Present the Best Case Against Christianity?

We have a current poll on this question. Dawkins is certainly the best known author so it's no surprise he will get the most votes. Any discussion of the poll itself? What do you think each author contributes to the debate? How many of these authors have you read? What other authors should be mentioned and why? Is the sum total of their cases good enough to debunk Christianity or will the arguments and counter arguments just keep getting better and better?

Here's the final tabulation:
