I don't find it more difficult to use or remember commands for than remembering how to accomplish similar tasks in some GUI (especially if that GUI is emacs). And unlike most GUIs (emacs may be an exception), I can trust that my knowledge of the git CLI won't become out of date when my GUI tool inevitably undergoes a UI redesign of some sort.

But more importantly, the CLI allows my typical workflow where I chain together a bunch of git (and other) commands in a row, allowing me to just type in, for instance, several different commits, their messages, and what files should go into each in one go without having to break my concentration by having to move around in some GUI between commits. Sprinkle in some stash manipulation and interactive rebases, compilation, and unit testing, and you'll really start to see how the CLI allows you to offload some of your working memory to your invocation in a way that a GUI just can't.
