Linux

That's not too hard a question for me, I've been using the same DE for years: KDE

MATE has been on most of my machines, except the BSD ones.

But past year or so, I have grown a fondness towards ctwm, and gradually migrated my machines to it, Linux and BSD alike.

It is not a DE, but the fact that I have to assemble my suite of software myself on my machines, makes the point of using DEs moot.

KDE, always

Used it since I switched to the Linux Desktop 25 years ago. Quickly tried gnome, and others, and hated it.

KDE is fast, efficient, looks awesome, is ready to work with, and highly customizable

Cinnamon by and far.

I've used so many distros and DEs I don't even know where to begin, but Cinnamon got me hooked for the long run. It's legitimately the most polished and "ready to run" DE I've ever used, yet still allowing for far more customization than Windows ever offered.

it's probably gonna be plasma6 by a hair over cinnamon on a rolling distribution. as much as people shit on manjaro here and on that other site, it has never broke on me--whether i update constantly or let it go 2-3 months between them.

but if the de and the underlying os are magically compatible, and those and programs kept up to date, never obsolete, and new ones appear for it as needed or desired... then sorry, it won't be linux... i'm going back to something like 95osr2, 98se or w2k.

KDE

Probably KDE, it's the most 'complete' feeling to me with settings and GUI for most things.

GNOME because it works out of the box like GNOME

Well, it's gotta be a tiling system. And a good one. At this point I can't function in a non-tiling environment. Specifically a manual tiler with an auto-tile a la i3 w/ i3-alternating-layout or a dynamic tiler that still let's you break stuff (doesn't really exist).

It's just a better way to use a computer, and I can't go back. It's so much nicer. I would stop using a computer before I go back to dragging windows around.

And that rules out most DEs. It rules out Mac OS and Windows, as well, but at least on Windows I can almost get by with Fancy WM. It's "okay."

And speaking of just getting by, that's Polonium with KDE. KDE is pretty good as an "environment," but it doesn't have a tiler that meets my needs, or at least I thought it didn't until recently. Then I discovered Polonium. It works pretty well. Used it for several months (and still do on one machine). It's very bare bones tho, and is hard to configure the handful of floating windows I do want like popups. So KDE is just scraping by.

GNOME on the other hand has the excellent Pop Shell 2. But well, GNOME is GNOME. It's buggy when you try to use it a different way than intended. God forbid I want Qt, Gtk2, Gtk3, Gtk4, and libadwaita apps to all look nice on my system! It's clunky, but the tiling is excellent at least.

Now you mention XFCE. So what about that? You could use i3 as the WM for Xfce. I used i3 for years and years and years as my WM and know how to build a DE around it. Why not use Xfce + i3?

Well, the thing is X11 is as good as dead, and while XFCE now supports Wayland, you can't use a tiling system with the Wayland version of XFCE.

So what does that leave me?

Nothing. At least for a full on DE, which is what you asked.

There is not a single (pre-made) Desktop Environment that suits my needs. Not a one. Either it doesn't support good tiling, is too rigid, or hasn't switched to Wayland.

My only options are:

• Roll my own DE built around Hyprland/Sway, and since I'm on nvidia, those aren't fantastic options (albeit Hyprland works a lot better on Nvidia these days), and that's what I'm using.
• Deal with the slight annoyance of the under-implemented Polonium in KDE

Right now I'm on Hyprland. May go back to KDE bc multi monitor is being weird on Hyprland rn.

My one hope is that COSMIC polishes itself up and gets to its first real release.

Always wanted to like gnome but never could, and xfce is fine but I much prefer KDE, it is verry likely that I'll actually keep it till my pc breaks.

This isn't even hard. KDE without a second thought.

I regularly try other desktops, and I regularly come back to the only desktop with any sort of reasonable thought put into it.

I'd rather not use a computer at all than use GNOME for the rest of my live.
For me it's KDE Plasma all the way.

I keep coming back to KDE time and time again. It's so easy to mess with, I can set it up exactly how I like it without much effort, and it always looks good because someone else did all the work making themes and widgets I use.

That said, I love XFCE, I'm just trash with CSS so it takes me forever to get it how I like, and on my Surface I can't get the scaling to work so everything is beyond tiny.

Plasma for the last decade. Then probably XFCE, then Cinnamon.

I try Gnome every year or so, but every time I get pissed off with it within a few minutes and wipe it off my machine.

LXQT. Why? Because: It is lightweight, consumes little resources, is quite customizable, and has full Ukrainian localization.

Maybe I'll switch to XFCE/MATE, but not if there are a lot of things not translated, or if the translation is worse than even Google Translate.

I'm using PopOS Cosmic alpha (not based on Gnome) on my new laptop and like it a lot so far. It has a few rough edges, but nothing I'd switch to something else over. (In fact, I did use the Gnome version of Cosmic until my previous laptop broke.)

There is nothing better than Xfce, if you dont like the desktop, at least Xfce allows you to customize. KDE seems interesting, but the last time i tried it, 10 years ago more or less, it was a bit buggy.

I've been using Mate ever since Gnome-2 transitioned to Gnome-3 and I didn't like the transition.

KDE plasma. Coming from 30 years of running exclusively windows it's just the most comfortable and easy for me to use (way more than Gnome). Easily configurable, works. Can't ask for more.

Cinnamon for 2 reasons

1. KDE is missing a lot of features which still only works in Gnome. Like the taskbar Calendar app syncing events with services like Google Calendar

2. cinnamon is extremely stable and doesn’t move your icons around when you connect to an external display with your laptop and the display has a different resolution.

XFCE
