I go for a terminal-first approach. If a CLI exists for what I want to do, I'll try it out.

If a GUI would be easier, I use that. If there is no CLI, I use a GUI.

At least for me, browsing the web, email, creating professional documents and developing large software projects mostly happen in GUIs. There are related tasks that are easy to shell out to, though, so it's not like I'm sticking to GUIs for everything.

I was never a fan of chatting using the terminal, so I use GUIs for that.
