Rollo's style resonates most with me (starting from the title of the blog and books). I have read much more of his material so he is by far the most influential to me personally.
Rollo doesn't sugar coat the (red) pill by any means, but he manages to cover controversial topics with respect even if he may not have the funniest take on those topics.
For example, how many of the high profile authors have the respect that Rollo has for those betas that simply believed what everyone had told them so far? I think Rollo is possibly the most influential and to that end it helps that he seems to have as a goal to help others unplug with his writing. His writing probably saved more lives than other manosphere authors.
Pook has some funny and insightful stuff from what I read, and possibly is more influential if only because he had an early start (to some extent he probably influenced Rollo and the other high profile authors, which counts for something I suppose). I want to read the full book of Pook.
I've read a bit of Roissy when Rollo links to him, Roissy seems to be very smart and he cracks me up laughing regularly, but I'm uncomfortable with the way he presents some topics.
