Having no "horse in this race", I would say, I find Damo's online persona a bit off-putting. I think he and his mate Adam do posture a bit to provoke reactions
As far as abilities go, I would agree with @forestofclarity that he probably focuses more on "power" than wisdom. Personally, fwiw, I know a few teachers who are far more humble and capable than both of them, but they are young (relatively speaking), and therefore have opportunity to grow (especially in the wisdom department). I also like Mark Rasmus a lot more than either of those worthies, simply because he is matter of fact and direct, and comes across as being a lot more genuine.
