For the end user, especially a beginner, there's 0 difference between them.
Shouldn't be the other way around? Beginners usually won't want to install DE's or other stuff by hand:
Linux Mint offers a Windows-like experience with cinnamon out of the box, and has several stuff setup by default like system snapshots and media codecs.
Pop!_OS is really appealing visually and very comfortable to use and setup.
Ubuntu, well, is Ubuntu. I'm not diving into it.
rPis for me aren't an option as there's no way to buy one here, first hand at least. And the electricity isn't really an issue as I pay it by estimates.
Also must say the server only purpose is to run long tasks without occupying my daily use PC. I don't have Ethernet internet either, so I can only put it online sharing connection with my laptop or with a (future) wireless expansion.
I use a bare git repo in .dotfiles/ that uses the home folder as a working tree, configured the repository to ignore untracked files, and then just add my dotfiles if there's a change.
To setup working dirs I aliased that to dtf
Get a hammer 🔨 . That will open it :)
Technically all the hardware (but microcontrollers) is open, as long as you have a screwdriver
Me jumping from debian stable to sid
Seamless transition from X to Wayland
Not technically a DE, but for productivity and full customization I use DWM (DWL is available for Wayland). It is super easy to use, keyboard centric and can be modified to behave exactly the way you want, as long as you patch it.
I was scared to install Linux as a daily driver at first. Then Windows Update screwed up my install and I said "Screw it, I'm not installing Windows again". Basically Windows took the decision to uninstall it for me :)
