I decided to give it a try on a new project and, although it seemed strange at first (coming from years using git), I fell in love with it and I'm converting all my own projects to fossil. It does everything other SCMs do. It also can do everything git does, but in a saner way.
Also, the self-hosting capabilities in a few MB binary are astonishing and you just don't pay for what you don't use. In my own repositories, I don't use chat nor wiki pages, but I do use forum, the ticket system and technotes.
The community and developers are very nice to answer questions too, and are open for suggestions. There is room for even further improvement and it is more a matter of someone showing up willing to develop the specific feature of the project.
