I am using nikola: https://getnikola.com/

The main reason is, that I really like jupyter notebooks and my blog began as experiments in Jupyter that I wanted to somehow preserve, i.e. http://notes.asaleh.net/posts/monoid-pattern-in-python/

Second reason is, that I like to experiment with format of my posts quite often (several were made in org-mode, i.e: http://notes.asaleh.net/posts/experimenting-with-purescripts...)

But it depends on what you want. I decided I want to write. So I focused on on writing and experimenting and try not to spend too much time on setup :-)

Good luck with your blog!
