Obsidian's "Outliner" plugin is really pretty good. Esp. assuming "Editing view" and "Live Preview" editing mode, (which combine for WYSIWYG).

I appreciate the standard, intuitive keyboard shortcuts for creating/removing bullets, indenting/outdenting, moving lines up or down, etc.

Also, you can use the built-in syntax for block references to kinda-sorta recreate the Roam block-based setup.

I've found it lacking, especially with kinda buggy interaction with the vim keybindings.

Obsidian's data model, a huge selling point to some, really hinders it too. Logseq's new db format let's you treat any block as a page, metadata and all which can be super helpful.
