I also tried logseq and couldn't really stick with it. Tried a few others like obsidian, joplin, Zettlr, Simplenote, even just vim and vscode with various plugins, but they all had their own drawbacks I couldn't get over, like a lack of built-in cross-platform support, syncing, encryption, not being open source, etc.

I eventually found Notesnook which strikes a good balance for my needs: open source, end-to-end encrypted, easy to use, decent UI, doesn't mangle code/formatting when copy/pasting, feature parity across platforms; I use MacOS, Windows, Linux and Android and they all have clients that have feature parity - even the web client is really good!

The only thing I would say it's currently missing is to release the source code for the server, but that's on their roadmap and actively worked on. It was this commitment to openness that lead me to try it and after some brief time start paying for it.
