I think I’m a bit of a dinosaur, but I’ve been making all of my notes in Zim for over 10 years. It’s not much to look at but I find the hierarchical wiki structure easy to navigate, and most of the functionality (todo lists, equations, version control integration, etc) is implemented by simple plugins.

in my opinion, a lot of these programs are too complicated - I tried Joplin for a while but I ended up spending more time organising my notes than I did making them.
