Notion vs Obsidian: After 18 Months with Both

Productivity Twitter has strong opinions about this. The Obsidian camp waves the flag of local files and infinite customization. The Notion camp points at collaborative features and a cleaner onboarding experience. Both camps are right about some things and blind to others.

I have an unusual vantage point: I ran parallel systems for most of 2025 and used each as my primary tool for extended periods. Here is what I actually found.

What Notion Does Well

Notion is a relational database tool disguised as a notes app, and its database functionality is genuinely excellent. The ability to create a table of projects, connect it to a table of contacts, and filter/view that data in multiple ways is something that no other mainstream notes tool does as well.

For team use cases, Notion is the clear winner. Notion has collaboration features, page-level permissions, comments, and version history that make it suitable for sharing knowledge across a team. When I reviewed this at a company level, Notion's collaborative infrastructure was the strongest in the category - better than Airtable for documentation use cases, better than ClickUp for knowledge management.

The templating ecosystem is also a real advantage. There are thousands of community templates covering everything from CRM setups to content calendars to habit trackers. For common use cases, you can start with a high-quality template and customize it rather than building from scratch.

Where Notion gets worse: performance with large databases (>5,000 items noticeably slows), the mobile app is mediocre, and writing in Notion has an editor quality that does not match dedicated writing tools.

What Obsidian Does Well

Obsidian's core proposition is local-first, plain markdown files. Your notes exist as .md files on your computer, readable by any text editor, sync-able via any file sync service. This is not a philosophical preference - it has practical implications.

Speed is noticeable. Opening a note in Obsidian on a large vault is instantaneous. Notion with a large workspace has a perceptible load time on almost every interaction.

The backlink and graph view features are genuinely useful for certain types of thinking. When I was researching a complex topic with many interconnected concepts, seeing the graph of how my notes connected to each other surfaced relationships I had not explicitly made.

The plugin ecosystem is extraordinary - there are 1,000+ community plugins for everything from Zettelkasten workflows to Anki flashcard integration to calendar views. If you want a custom workflow, there is almost certainly a plugin for it.

Where Obsidian struggles: the initial setup is unintuitive, there is no native real-time collaboration, and the mobile app sync requires paying for Obsidian Sync ($8/month) or setting up a manual sync solution.

The Setup Cost Difference

This is the most underrated factor in the comparison. Getting useful output from Notion is quick. Their onboarding is well-designed, templates are immediately available, and the learning curve to basic functionality is flat.

Getting useful output from Obsidian takes longer. Setting up a folder structure, choosing a sync method, picking plugins, and configuring the experience you want takes several hours for a new user. Some people find this process enjoyable. Many do not.

For teams: Notion's lower setup cost is multiplied by headcount. If you have 30 people adopting a tool, the difference between 1 hour and 5 hours of onboarding per person is material.

Where I Landed

After 18 months, my conclusion is that these tools are for different things:

Use Notion when: you need relational data (project tracking, CRM, content management), you are working with a team, or you want templates and a managed experience.

Use Obsidian when: you are building a personal knowledge base for long-form thinking, you want control over your data, or you have specific workflows that benefit from the plugin ecosystem.

I currently use Notion for project management and team documentation, and Obsidian for my personal research notes. The two-tool combination is slightly annoying. It also means I am using each tool for what it is actually good at, rather than forcing one tool to do both jobs.

If I had to pick just one: Notion for most people. Obsidian for people who think seriously about knowledge management and are willing to invest in setup.
