> Supports ... code blocks with syntax highlighting.

Based on the documentation and the screenshot next to it, I don't see how it differs from Obsidian on this point.

A Markdown code block in Obsidian is going to be highlighted as expected.

Actually it appears that they both relies on Prism to achieve this :

- https://help.obsidian.md/syntax#Code+blocks

- https://github.com/suchnsuch/Tangent/blob/main/apps/tangent-...

I've used Obsidian and Tangent. For whatever reason, I've found Tangent's code highlighting brighter, more colorful, and (maybe hence?) more easily readable. Obsidian is more muted. Steve Jobs would have preferred Obsidian.
