Tina is not a CMS
I love static sites and made some using Hugo. A year later i've started working with WordPress and its ugly/nice (it depends) Gutenberg editor and to be honest, having a look at the quality (yes, there are a lot of excellent plugins and a lot of bad ones) and the availabilty of plugins,i think WordPress is the only platform to go for business oriented websites where seo, caching and other things matters a lot. I've been using wp on production and i'm very happy with it and even if it's far from perfection, even common users learn easily how to use it.
Static site generators look like something build for developers instead of non-developers users.
What i really miss on WordPress is the capability to produce a static site from a WordPress installation and use netlify for hosting. I know there are some plugins for that purpose but i still haven't tried them.
