FWIW ~ Matt Shaw over at Delicious Brains started quite a nice series of CMS reviews called Self-Hosted WordPress Alternatives back in October. He's only reviewed three so far - Craft CMS, Grav CMS and October CMS, and while they are not what you might call "exhaustive", they are quite detailed. Maybe because he is a WordPress developer, and his views seem a little biased ~ at times ~ what was interesting to me was the comparison he made with WordPress. I guess, of necessity, developers look at things differently.
