I have used a number of distros over the last 15 years. Once I found one I liked, I stuck with it. I understand the package manager, some of the special features of the distro I use and I don’t really have time to relearn this every couple of months on new distros.
If I want a different “feel”, I change my DE. But that’s about it.
I have been using terminal almost exclusively for about a decade or more. But, when I started I just decided to do it. And that meant that every time I wanted to do something, it would take me forever because I would have to look it up. Eventually, I got faster and faster and now anything I want to do with a gui, I can almost certainly do faster with terminal.
