None of the static-site generators I looked at really competed with WordPress on a feature-by-feature basis.
WordPress is easy to set up, supports users and comments (if you want them) and has a lot of really nice features and plugins. WordPress is also slow and a pain in the neck to maintain, but I can understand why people might think the tradeoff is worth it.
I also run my site[1] using my own custom-built generator and I haven't looked back, but even I sometimes miss the ease-of-use that my old WordPress site provided.
I built my own custom static site generator (python + jinja2) for running my side project[1]
I just git push and Netlify picks it up. Simple, to the point and no JS.
