Since I've often heard the rebuttal that one can find the same advice on TRP on plenty of other sources...

What struck me about RP advice more so then any other dating advice I had ever glanced at was that it seemed to understand my own mindset in regards to women and how to fix it. You could take all the stuff it tells men to do out of it and place it a vaccuum, and it might be decently successful. But it wouldn't have the effect of saying to some guys, "Yes, I know how you're thinking, why that's wrong, and how you could end up succeeding instead."
