Robert3945 How difficult is learning necessary terminal commands? Usually not difficult, but there is a learning curve. However, there is with anything new that you encounter.
I recommend checking out Linux News on a frequent basis. There are sometimes links to command line tips on the site. Another option is to purchase a book on using the command line. I like this one. If that one seems a bit too much for you, there's this one.
I've come from a casual Linux mint point of view that nearly everything can be performed through software rather than commands. I think that could be said for most Linux distros. However, there are instances where using the command line is preferable or more efficient than using a GUI.
I've also encountered instances where the command line was all that was available to me. For instance, I had a Dell Inspiron laptop that had a AMD GPU. Every time there was a kernel upgrade on Debian Stable, when I rebooted I would not be able to login to the desktop. I had to manually re-install the AMD proprietary GPU driver from the command line.
If you ever decide to install a barebones Debian installation using the Debian Network Install method, only the command line will be available to you afterwards.
You will be doing yourself a huge favor by embracing and learning the command line. I'm not saying that you should give up GUI, but knowing how to use the command line will enhance your Linux experience. That's my opinion anyway.
...another rolling release distro? I think Solus is the easiest rolling release distro I've used. Based on your posts, I'd say you want to steer clear of Debian Unstable or Arch Linux until you gain more experience, especially working on the command line.
No matter what Linux distro you choose, if it's new to you there will be a learning curve. Don't try out a new distro and expect to be as proficient as you were with a previously used distro.
