For me, and this is very subjective of course, I prefer the most simple but solid editor, and Nota's editor is great. The little things; excellent preview editor, cmd + d to multi cursor select the next occurrence, option + up/down to move lines around, just like in VSCode. It just gets out of the way and let me do my thing.

Also what I missed in Obsidian when I tried it. I will also simply not use all of its fancy features, not to say they aren't useful, just that I'm not that organized haha.

I also really like how Nota looks; neutral, under styled, minimal. This is oddly important to me haha.

Nothing against Obsidian though, it seems to really excel in its purpose of knowledge base building.
