I recently started using the Mercurial open source project, and I'm impressed with its capabilities. The branching and merging features are exceptional, and the performance is top-notch. The documentation is thorough and easy to follow, which has helped me get up to speed quickly. The user interface is intuitive, and the community support is great. In my opinion, Mercurial is one of the best version control systems out there.
