Your review seems to be more an ad-hominem attack on Huberman than an ad-hoc review of his book.
There's no need to be surprised that reviewers didn't mention Atheist's Bible as a better starting point, because it's not.
Since I haven't read Konner's book, I wouldn't take the job of judging whose better.
I'll just point the following differences, as can easily be seen with the help of the Look Inside feature on Amazon:
1. Both books were first published in 2007, so none of them seems to rely or be influenced by the other.
2. Huberman's book is almost twice longer.
3. Konner's book contains no background or research on the contributors, other the occupation, birth date and death date if relevant, for which you'll have to look in the end of the book in a different section, whereas Huberman's book contains a few sentences or even paragraphs about each contributor prior to the quote, and usually not conventional stuff but well researched info that at times is very funny. A fine example can be seen on the very first item - the background info of the contributor on page 1. LOL
4. Last but not least - Huberman's book contains a list of sources (books and web sites) both for the biographical information and the quotes, which Konner's book lacks.
So, bottom line - I think it's a very worthy starting point...
