I use #Obsidian. I used evernote briefly about a decade ago. When I decided to get my information out and use something else I found the export and conversion process frustrating. It was not something I wanted to repeat. 

Now my notes are in Markdown and I can access them in Obsidian or anything else I want. Obsidian's linking and graphing add value while leaving the notes accessible to other tools. There is an Obsidian plugin for posting notes directly to #nostr. I have not tried it yet.

Whatever tool you choose, I suggest ensuring your notes are maintained in an open, accessible format.

 I've used many of them. Then I was very intrigued by Obsidian. But after that, I've found the best one for MY purposes -- and that's Logseq.

Logseq is very much like Obsidian, but I like that it is fully open source. I also especially like outline structure of the notes,  to go along with the default journal entry dates. It serves me well for what I need it to do (including taking notes on podcasts and sermons, recording ideas, and outlining my thoughts for writing blog posts). 

 I don't think I've heard of Logseq before. I was a fan of outliners for many years, all the way back to Dave Winer's OPML editor. In my corporate white paper writing days I worked almost exclusively in MSWord's outline mode for the first draft or two.

I will say it looks interesting. I will go thru the docs. What are you using to sync between devices (if you are doing that)? I'm using #SyncThing with Obsidian, which has worked fine for my needs. 

 I also use Syncthing for my Logseq, as I did with Obsidian.
