I guess, in my experience with his information, his lens specifications, distortion correction numbers and reviews on AF speed and sharpness performance have been fairly accurate and useful to equipment I wanted to buy and have used.

His tutorials are descriptive for starting out too...

I do see what you mean by being opinionated. I've read tons of reviews saying "sharpest mid range zoom EVER" but I don't really read his intros... I usually skip to his pictures, numbers and reviews on performance. But to each his own, I know he's not perfect or anything, haha.

PS - Merry Christmas everyone.
