I agree with you general point, but I think for your specific examples you may just not have used the best GUIs.
Magit https://github.com/magit/magit is definitely the best user interface I've tried for version control. I still drop to the command line occasionally, but it's not as productive unless I'm doing something unusual.
SQL Server Management Studio is also much better than any command line database tool I've used. For any action you can do in it, you can hit a 'generate script' button which you can use to automate what you just did. This is a fantastic feature, because using the GUI becomes a better way to discover and understand the CLI underlying it.
