I think the main advantage of GUIs in general is a contextual, curated explorability that is often lacking in CLI tools. The GUI is stateful, allows the user to click on things and prod it, and hopefully shows the most frequently used features for that context. This allows even complete newbies to be productive almost immediately.

For something like git, the slightly more visual representation is a benefit to many, too.

I'm not here to knock CLIs, there are a set of tradeoffs to be made, and CLIs win in many cases (flexibility, scriptability, being able to copy snippets you frequently use, etc). The above does tend to hold true, however.
