I'd have to disagree with you on that one. I recently migrated to Fedora from Windows 11, which gave me the chance to try Plasma, GNOME, and a couple other desktops.
Plasma is exactly what I don't want in a DE. It’s extremely configurable, but also overwhelming, and I don’t think that’s something the average user would feel comfortable navigating.
I ended up choosing GNOME. It feels visually cohesive, and the design is much more opinionated — they’ve clearly made decisions about what should and shouldn’t be part of the core desktop experience.
I settled down for Fluxbox back when it was still actively maintained. Ever since its death I have been using IceWM, mostly because it is so much faster than GNOME or KDE-Plasma. I think both KDE and GNOME went into the wrong direction though. GNOME because it forces everyone into the shell-centric way to use a computer, similar to a smartphone (the whole UI constantly reminds me of a cloned OSX smartphone interface, for GNOME3 that is; mate-desktop is more of a desktop-centric UI but sadly the project slowed down immensely in the last few years, aka becoming more and more inactive really). KDE indeed has too many configure-options, but the defaults are more similar to the 1990s desktop-centric era shaped by Microsoft. I like that approach more than GNOME although in the last few years KDE also went the wrong way, largely due to Nate, David Edmundson ("our destiny is systemd"; that reminds me of Firefox "you must have pulseaudio for audio on youtube", how strange I can hear audio via chromium/thorium just fine, so what are the Mozilla devs thinking here ... not much, that is for sure) etc...
so just.... don't reconfigure it?
If the defaults work: sure. Do they, though?
I don't mind changing things on KDE, but the defaults are useless to me. Too many annoying things, all those time-wasting gimmicks, on-hover uselessness. It is clearly written for another target audience, e. g. Average Joe coming from Windows. While that is fine perhaps for those users, to me the default is useless. And I think many others feel in a similar way. To me the defaults in GNOME are even worse though, so it is a lose-lose scenario. But things can be configured, so that problem can be solved for most settings or behaviour; I am just not convinced that sticking to the defaults works that well.
Yes, they do. I've used Plasma on a couple of computers for a while, and the defaults have always been fine for me.
