For a small site with relatively technical administration, Grav is unsurpassed. I've been using it for years for my portfolio and various side projects, and it is a joy to build with.
For a larger site with multiple contributors, I'd probably still stick to Wordpress, though. Its admin experience and ecosystem are just too mature to not take advantage of.
This is why I recommend people look into Statamic. It's absolutely smaller than WordPress, but it's set up for the professional community so there is an environment of plugins, themes, etc. It's also built on top of a Laravel foundation, so you're not stranded having to do things "the WordPress way".
