Yes, I switched to TiddlyWiki a year ago, and haven't regretted it. I tried Evernote, Notion, Org-mode, Dynalist, Zettlr -- and looked at Dendron, Roam, Obsidian and so on.

I think what separates TiddlyWiki and Org-mode from the rest is that they are easily "hackable" and have more powerful syntax, but are also more demanding on the user.

You can modify the UI and add features inside TiddlyWiki itself, using only TiddlyWiki syntax and Javascript. Like if you want backlinks to be displayed at the bottom of every note in a certain way, you can do that.

Markdown is a very limited language when you think about it. (Most of these tools would be better off using AsciiDoc.) TiddlyWiki's WikiText has macros and widgets that let you do things Markdown never will, and your "notes" can become interactive and dynamic.

See e.g. <https://groktiddlywiki.com/static/Macros.html> and <https://groktiddlywiki.com/static/Widgets.html>.

TiddlyWiki allows you to create a very sophisticated, tailored system for managing lots of different things. But when you begin, it's a pretty steep learning curve, and you'll need to put in more work than when starting with Obsidian, of course.
