I used both for a year. Here's who each tool is really for.
| Notion | Obsidian |
|---|---|
| Collaboration, wikis, databases | Personal knowledge, local files |
| Cloud-first, works everywhere | Markdown files you own |
| Great for project docs | Great for linking ideas |
| Slower with large workspaces | Plugins for everything |
I use Notion for team docs and Obsidian for personal learning notes and blog drafts. Splitting by purpose stopped the "which tool?" debate.
