GNOME 3 doesn't have desktop icons, if that's what you mean. And yeah, that version number sounds about right. They used to version it as "3.38”, but then instead of "3.40", they decided to call that version "40" and continue from there.
KDE is very much the opposite of opinionated. It comes with a Windows-like layout by default, but you can do pretty much any layout you want with it. People rather complain that it has too many options.
I would definitely recommend giving it a try, or at least checking out some videos. It happens a lot that people who dislike GNOME, then try KDE and are completely flabbergasted why that's not the default.
