I personally prefer SimpleScreenRecorder: http://www.maartenbaert.be/simplescreenrecorder/

...Because it lets me record audio using the Opus codec.

I also edit the videos using kdenlive: https://kdenlive.org

It all works pretty well. You can see examples of the end result in my YouTube channel:

(mostly videos of modded Minecraft tips and HOWTOs; all totally harmless and no foul language)
