IMO: Obsidian does a good job in making me reflect and review notes, but not enough to prompt me to write more of them. Logseq does the exact opposite.
There's nothing wrong with Obsidian per se, but that's probably the crux of my issue with it. I'm not very naturally inclined to taking notes in the first place, and Obsidian just hasn't made me take that many more notes than I used to.
Logseq on the other hand has an editor that makes it hard for you to even write longer / multi-line blocks. In some ways, I suspect that writing in bullet points or smaller blocks encourages shorter but more frequent note writing, and my brain seems to respond well to that. Obsidian can technically do that to some degree, but the editor doesn't do enough to make me write shorter and more atomic notes, even with the Outliner[0] plugin installed.
