I’ve been using it for forever and also used it for DnD, based off of…what’s his name, one of the bigger DM guys on YT. It works great.
I’m using Obsidian for work since cloud note apps are blocked and I don’t like it as much. It works, but I’m not as wild about it.
One issue I recently had with one note is that I wanted to export a section to share on the web and wasn’t able to do it and the web interface doesn’t really let me do the management that I need. My work machine is my main one right now, so I’m stuck with what I’ve got. That all being said, aside from privacy, there isn’t really a direct reason to change.
But I’m not super wild that MS is reading my notes since I’ve also used it as a diary at points. I’ll have to figure that bit out later.
