Using the CLI lets you automate things a lot easier, which makes you a better engineer.

Using a TUI however makes you an absolute beast mode rockstar engineer

All the good GUIs have a license fee.

To me, your choice of worlstation OS says a lot more about your priorities.

True

luci ui on openwrt is so good

I use the UI for some stuff and then the CLI for other stuff.

CLI is great for bash oneliners and combing through logs or text files.

Sounds like someone has DNACenter with fully deployed ISE and SDN fabric. I'm honestly a little jealous.

Yes, i also prefer GUI.
