For a local repository it might not matter much if you don't care about a readable git history, but generally I tend to advise againt using git GUIs, and prefer to use the command line directly. Git is confusing and hard to learn, and GUIs make it even harder IMO to learn things "right" by hiding what git features it uses (fetch, pull, merge, rebase, etc.).
If you want to be able to have a readable git history, contribute to open source git repos, or work in a bigger team using git, you won't regret learning the basics of the git command line.
