Not the parent commenter. Git the version control system is superb, fast, robust, well-thought out. Git the CLI tool is by far one of the worst CLIs I have ever had the misfortune of using. I think the one-dimensional, string-y command-line massively complicates mental and reasoning models for a tool with a fundamental data structure—a tree—that is multi-dimensional.

A powerful Git GUI makes even moderately-complicated actions like cherry-picking, interactive rebasing, and even ref-logging absolutely trivial. In fact it was precisely said GUI tool that allowed me to develop an intuition for how Git worked internally; the CLI does no such thing.
