I'm running Pop!_OS. I tried Mint and EndeavorOS. I found that I don't like vanilla gnome, and while I appreciate KDE, it's too Windows-like. Which is contrary to what I'm trying to do by switching to Linux in the first place. So Pop is perfect for me.
Obsidian. Plain text files with as many or as few plugins as you want. All versions of the app look and behave the same (other than mobile, but at least android is kinda close). Nothing stored in a database file, no manipulation of the text files themselves (looking at you, Joplin). I'm open to another option but so far, nothing is as elegant and platform agnostic as Obsidian.
I really like it. I tried several distros for my first dedicated desktop Linux machine and pop was the one that clicked. I like that it's not trying to mimick windows UI, and only sorta behaves like macOS. Everyone else was too close to win10. Which I understand is a selling point, so to speak, but I'm so sick of windows that I wanted it to look and act differently.
