SourceTree is a powerful Git GUI client that excels in Git support and offers robust features for branching, merging, and integrated terminal access, making it ideal for complex Git workflows. In contrast, TortoiseHg is a solid choice for Mercurial users with a simpler interface, but it lacks some advanced features found in SourceTree, making it better suited for smaller projects or users focused primarily on Mercurial.
