I have found very little I can do in Obsidian I can’t do in Devonthink with greater reliability.
Obsidian’s Dataview can be fussy. DT smart groups are not.
I wish DT had a native local node map, but the see-also and links inspectors reveal basically the same information.
Tinderbox does something neither DT or Obsidian will do. Notes in Tinderbox can have sub-notes. In another thread, that’s why I suggested it would be nice for DT to display a group annotation in the preview pane.
All of the above is opinion, of course, and likely flawed.
