The main impediment for knowledge retrieval in apps like obsidian/roam etc. are that the notes cannot be retrieved easily, especially as the number of notes scale. (Maybe, Obsidian users might disagree with this point, but that was my assessment.)

Dendron is built for ease of retrieval of notes. It is built mostly for devs. Now, I can retrieve forgotten syntax easily in Dendron when compared to other apps. The fact that is is built on top of VS code helps.
