GitKraken is a visually appealing and feature-rich Git GUI client that runs on Linux, Windows, and Mac. Here are five versatile options: GitKraken. I'm not saying Magit is the best git client, since that will largely depend on what you're looking for in a client, but at least for me it was. If you work on multiple operating systems or collaborate with developers using different platforms, cross-platform Git GUI clients are the way to go. This also makes it pretty fast to work with. Some GUIs might have things you want to copy/paste but it's a button or graphical element, making you have to click on something else to make that text interactable. Git comes with built-in GUI tools ( git-gui, gitk ), but there are several third-party tools for users looking for a platform-specific experience. Commit extend/reword is another example of some of the small niceties that add up. Rather than going through the usual hoops of starting a new branch with that commit and resetting master, Magit provides a "spin-off" and with just a few key strokes, your commit is in its own branch and master is back to normal. For instance, sometimes I do all my "merging back into master" work so I can start a new branch, start working on a new feature, commit, but forgot that I was still on master. While they might only represent a small percentage of your day-to-day workflow, it's nice when you can use it. It has a lot of convenience functions for a lot of the standard git commands. Interactive rebasing is also mostly done the same as doing it the CLI way. In Magit, just tap `f - p u` and you'll get the same thing. As an example, if you want to fetch and prune from the command line, you would call `git fetch -p` or `git fetch -prune`.
It does this while providing real-time hints/cheatsheet style documentation so it makes discovering some of git's functionality easier. First, it will appease those who suggest "just do it the CLI way" because Magit's "Transient" interface mostly just maps mnemonic keys to git commands and their respective flags. Although this does require users to learn how to use the command line, it is often faster than using other types of GUI clients since all operations are performed directly from the terminal window. I love UnGit because of its simple operation, favorable graphical user interface (GUI), smooth performance, etc. I actually tried to stop using Emacs in order to unify my tooling but I couldn't wean myself off, just makes working with git way too easy for me. Command Line Interface (CLI) Clients: CLI clients provide a way for users to interact with Git through text-based commands. I was not an Emacs user and Magit became the gateway drug that led me down that rabbit hole (I now have a 1000+ line literate config). I have used Jetbrains' IDEs, the CLI with fish+abbreviations+fzf, Git kraken, tig, and SourceTree. The learning curve is steeper, especially if you also need to learn the basics of Emacs (shouldn't take that long, really), but in the end I think it was totally worth it. The interface is primarily keyboard driven, rather than mouse driven (some basic mouse interactivity can be enabled).
Depending on how flexible your definition of "GUI client" is, you should give Magit on Emacs a shot.
