Obsidian for power users, Notion for teams
Using all three for different purposes:
- Obsidian: Local-first, best backlinks, highly customizable with plugins. The graph view is amazing for connecting ideas.
- Notion: Best for collaboration, all-in-one workspace. But privacy concerns and subscription costs.
- LogSeq: Open source, outline-based, great for hierarchical thinking. Still maturing but promising.
My choice for second brain: Obsidian – the graph alone is worth it.
