Obsidian has made managing my work significantly easier
For someone who struggles with organization, it really helps

There are a lot of note-taking apps out there that I've tried, but Obsidian is the first to have finally captured me. I don't need overly complex notes, I just need something to help me keep track of my day-to-day life... and this finally does it for me in a way no other app has before. //

Key features:

• Sync across devices
• Data control of your files/data
• Ease of dropping a note from your phone or desktop
• Ability to organize your notes based on your method

I feel like the author was trying to convey they chose a new note taking methodology that worked for him.

You can apply a note taking methodology to anything, including the trusty pocket notebook.

This author chose a new methodology and chose to use obsidian. That's it. Not that obsidian is better at note taking apps.

So far for the literal speed to note taking onenote and Trello seem to be the winners. They also sync flawlessly. There may be other apps too.

All that being said, you can make a mess of your notes in any app too.
