With reviewers, I now first look at the style of shots they take. For example, with Jared Polin, I trust his opinion on sports / action photography, but not landscape, street, or architectural photography. Or for portraits, my go-to is Pye Jirsa.

About Ken Rockwell, I've heard him described as a "black and white photographer shooting in color" - he likes contrast & texture, and generally shoots stuff that would look better in b&w.
