What I like the most:
- ultra fast UI thanks to their robust infrastructure
- full fledge editor for taking notes
- and the best of the best: the diagram/schematic editor
- the native Mac OS and Windows apps
The biggest differentiator with Gitbook is that here you don't have to install anything to get all these cool libraries, all is included.
It's the perfect Documentation and Knowledge base tool for me.
Also the rich integration is a huge plus:
