I understand the argument being made, but I kind of disagree. Yes, picking a DE in which you'll be comfortable is really important (and often an undervalued aspect of using Linux for the first time), but I think that the time you need to spend self-maintaining your distro is more important, and is also prone to make-or-break your first-time Linux experience. That's the most important factor on whether a new user says "I love Linux and want to continue using it" or "I fricking hate Linux, it's filled with a bunch of problems, I'd rather just use Windows instead". And that's why it's important to recommend beginner-friendly distros, as to avoid frustration of newcomers, because those are more manageable (unless those newcomers want the frustration of managing something that they don't quite understand :)

Does it matter which one in specific? No, and it's probably at this point that the DE and visual looks should kick in.

I agree with that take until...

The “what you go for it’s entirely your choice” mantra when it comes to DE is total BS. What happens is that you’ll find out while you can use any DE in fact GNOME will provide a better experience because most applications on Linux are design / depend on its components. Using KDE/XFCE is fun until you run into some GTK/libadwaita application and small issues start to pop here and there, windows that don’t pick on your theme or you just created a frankenstein of a system composed by KDE + a bunch of GTK components;
