Earlier quoted context omitted.
I don't see any reason why someone would use OpenBoard over AnySoftKeyboard. It would of been nice if there was an explanation of what differentiated it. If someone just wanted a different looking keyboard they could just have created a new theme for AnySoftKeyboard. AnySoftKeyboard also is the only open source keyboard for Android that has gesture typing. Which is something I grew to love from when I used Gboard.
Swyping didn't work reliably when I tried one year ago, so I switched back to one of the keyboards of my phone (SwiftKey because I find it slightly better than Samsung's one.) Did they improve it in the last releases?
Alas, I wish it were. This is all that's missing IMO.
