I've tried 'em all. And I am always on the lookout for new apps that can do what I want. So far, Obsidian is the best.

• Joplin: adds meta data to your text files making it nearly impossible to find anything outside of Joplin unless you export

• Logseq: the closest substitute to Obsidian. The android app is almost unusable in my testing. And it's an outlined based note app, so it requires a different mindset

• Silverbullet: such a neat project. The PWA runs great on every device I've tried it on. That said, I find it hard to navigate and will require more learning to take full advantage of its features

• Nextcloud Notes: decent if you already have an instance running. Not worth it just for Notes though. It's very spartan, feature-wise

• Quillpad: the closest Google Keep alternative I've found so far. Does require Nextcloud insurance to sync though. At least currently.

• Acreom: very cool project. Similar to Obsidian and Logseq. Local first.....unless you're on mobile, then you are required to have an account and use their sync.

• Notesnook: has great features but does not store the notes on plain text (due to encryption), which is a deal breaker for my use case

• Memos: very easy to selfhost. Think of it like a personal twitter feed. Stores entries in a db file, so it's out for me

I tested others, and many didnt last long enough in my testing to even be worth writing about. I find Obsidian's folder hierarchy easier to fit around how my brain works. And the plain text files in folders, maintaining the hierarchy, is a killer feature for me. Lots of folks self host a sync solution. And I want to but am currently paying for their basic sync plan of $5/mo.
