What is Reddit's opinion of Tkoutline?

From 3.5 billion Reddit comments

One of the reasons why I switched to Linux was due to privacy concerns, NSA, yada-yada. I think it would contradict my efforts to use a web app again - at least one that's not self-hosted. As far as web apps are concerned, there's a good one by the father of outliners, though: Fargo. Still, I want to keep control over my own data.

There was one outliner in your list that I haven't tried yet. tkoutline looks interesting from what I've read so far. I'll try that one out, but I'm still up for other suggestions.
