Yes, I have tested Logseq and even donate to them monthly. However I don’t use it actively. Reason is that I just can’t figure out a way to store my quotes and my opinion about them from books the same way I do it in Notion.

Basically I store my quotes like this:

Inside each quote I write my opinion or the summary of the quote in my own words, etc.

And then for the books I have it like this:

And inside each book I have the quotes linked:

So yeah I haven’t found any way in Obsidian or Logseq to replicate this structure. It’s always something simliar that’s not working the same way and feels off and only with tweaks, custom CSS and stuff like that.
