Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Allows you to stay in the terminal
If you prefer to do most of your development inside the terminal, changing windows to move to a GUI git client can be annoying. Since tig runs inside the terminal, that's avoided.
Pro Fast
Pro Vim-like bindings
Pro Available in Homebrew
Can easily be installed with homebrew simply by running brew install tig
Pro Works on any platform
Pro Visual commit mode
Allows for interactive staging of files or hunks and deleting of unstaged or non-git tracked files. Hunk size slider allows staging/unstaging individual lines, letting you stage pieces of a file easily.
Pro Fast GUI
Responsive even with thousands of files or large binary like files
Pro Understandable trees (branches etc.)
The visualisation of the development trees makes git a lot more useful. The command line is good for a lot, but trees are for GUI clients like GitX.
Cons
Con Steeper barrier to entry as compared to a GUI solution
Since you have to get used to working in the terminal (if you are not already used to doing that) and learn the commands, it has a steeper learning curve than GUI clients which are usually more intuitive and easier to grasp.
Con Clumsy staging workflow
The staging workflow in GitX-dev is kind of clumsy and unintuitive in the opinion of some. (others love it)
