After trying out Cosmic, Gnome,KDE Plasma, and Hyprland, I feel like plasma is the most usable for me coming from Windows. It solves the gripes I had about lack of customizability while still starting me off with a familiar homebar. I will be going back and forth with gnome for a while.
I really like gnome and the sliding desktops, and all the extensions seem to make it very customizable as well, but not directly like plasma, instead you mix and match (or make) extensions to get the look you want. (correct me if im wrong, I used it for a day)
Hyprland seems very nice for multitasking but the keyboard focus of the presets ive tried doesn’t really appeal to me, I like being able to just use my mouse sometimes.
Cosmic, is definitely an alpha and im interested to see what it becomes, wont be using it now.
KDE is the easiest for coming from Windows, you almost never never need the command line or anything “extra” to customize it (beyond what even Windows will allow).
GNOME (especially in Ubuntu) by default is more Macintosh-like which might appeal to some people, it’s “simpler” but any customizations will require navigating the add-ons (and in my experience inevitably the command line too).
I think KDE is the one for most people who just want a functioning PC. GNOME could be good for the PC you might make for your parent. Bonus points for an immutable distro which are even harder to break.
Trying cinnamon and it might be the superior parent rec, its basically older windows, very straightforward ui, not flashy, Gnome (at least the default i had) didn’t have a start bar and required clicking the windows button to see clickable stuff that weren’t icons. With extensions it can be basically windows or mac tho. (so if you directly setitup for them or guide them its more modern feeling/superior)
Zorin is another distro that (very successfully imo) does a windows-style taskbar with GNOME and is parent friendly, though like I said before, I think today I would go with something immutable for a non-techie because they’re very hard to break.
Universal BlueAurora KDE, or bluefin gnome are what id prob reccomend to any non gamers trying to use Linux after looking around, bazzite for gamers who dont want to tinker, cachyos for those who do. Seems like a straightforward way to get up and running, cachyos was hella easy to dualboot tho, universal blue doesnt seem to let me load a live os from my usb with a graphical installer, that was super helpful with cachy.
