Hello there,
I have not heard of the others, but I have seen the Rich Jerk's ebook/program, and although I do belief the guy needs to pull his stick out of his you know where (although I guess that's his gimmick for marketing, so maybe not, haha), I do agree with much of what he has to say.
Good luck with it.
