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.
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.
