PG doesn't brag incessantly. Both produce a large stream of consciousness that may have nice tidbits and sayings. But the real test is to see if such ideas can be turned into a consistent algorithm or formulas that one can test via historical scenarios or in practice. Just because you have a cool-sounding idea doesn't mean it will usually fly in practice.

T has made some interesting claims about success in business, but they conflict with works such as Dale Carnegie's classic HTWFAIP, which better matches life as I have observed it. But some trolls and demagogues do gain success as counted in money and power. There is more to one strategy in life, but HTWFAIP is probably easier for the average person to use effectively. Plus, trolls and demagogues tend to generate new regulations that prevent later T&D's from pulling the same tricks. There's kind of a first-mover-advantage to jerk-hood, like people selling Purell at huge markups.
