My verdict: the Swiss army knife of productivity, with a warning.
Notion is excellent for centralizing knowledge, but it's also a 'productivity vacuum' if you get carried away with customization. The Swiss army knife of modern productivity, but beware of the trap.
It's a 'productivity vacuum' if you get dragged into infinite customization. Ideal for centralizing knowledge, but don't spend hours tuning your dashboard. The free plan is generous at first, but per-user pricing can quickly explode.
What I like less: the infinite customization trap. You can spend hours building the "perfect system" instead of working. Notion can be slow on large databases. The mobile app is less polished. And for pure note-taking, Obsidian is more powerful.
My advice: use Notion for documentation and team wikis. Keep it simple, don't fall into the trap of ultra-complex templates. If you want advanced personal note-taking, look at Obsidian. And for task management, a dedicated tool (Things, Todoist) is often more effective.
