OBSIDIAN IS AWESOME -- till death do us part :-)
If you are a power user of KM tools and will invest the time to make it be just as you want it... there is NO OTHER CHOICE in 2020. And the fact that it is all 100% local, simple markdown, and free forever means I will probably never leave. (I have never said that about any of the dozen other tools I have used over the years).
Still it must be acknowledge, you don't even get a real key bindings with Obsidian, you need to invent your own scheme, and the docs are just not complete, so it does not come with batteries included. Still in just two weeks I was able to find and use more plugins and more capabilities than I ever got from Evernote, or others.
If you are a power user of KM tools, this is the tool for you!
