I use logseq for the most part - I have multiple graphs for each domain I'm interested in. I've learned with time the way that I should structure my graphs to make the most sense, the best ways to actually use the stuff that logseq offers and stuff. And it didn't take that long either, I've only done this for the last couple months. It's open source and passes under enough eyes for me to be comfortable with it.

• I miss some things though - Adding in multiple files (like PDFs or images or audio) is still a pain.
• The user discussion forum is where my dreams go to die (devs are a bit conservative in considering new features). - The UI looks like it was made by a Soviet survivor of a nuclear armaggedon (Utilitarian to the point of blandness).
• A whole bunch of the plugins come out of china (Or atleast chinese sounding usernames) (I hope that's not racist), I assume because it has a large userbase there; and I don't really vibe with that.
• It has relatively fewer plugins than obsidian does.

That's pretty much everything I can think about off the top of my head. Sorry for the wall of text.
