Linux

I've been preferring KDE lately tbh. Very flexible and familiar. Still don't know what that activity thing is for though lol

I'm not aware of any distro that ships this by default yet, but Hyprland is my favorite visually so far. Excited for it to continue to develop. I'm sticking with Sway for now, Hyperland's grouping isn't nearly as extensive as Sway's tabbing and stacking, hopefully that will come eventually, but Hyprland sure does look amazing.

My vote would be EndeavourOS with KDE Plasma.

XFCE

Pop yea? Yeah?!

I'm more of a window manager person myself (Qtile to be precise), and I imagine that's not really what you're looking for here, but DE-wise from what I've tried I like KDE and XFCE the most

Yeah, this may not be helpful for you but the best GUI is a tiling window manager (compositor?). Using it for 2.5 years, never looked back. I really recommend Hyprland for everyone to try, it's the perfect thing we've ever needed.

I've been enjoying Gnome using !pop_os@lemmy.ml. It's not perfect, but good enough. The preinstalled tiling extension also makes using a full DE bearable without spending hours customizing a WM.

I'm looking forward to trying out Cosmic, which I have high hopes for.

I liked zorin os

Absolutely love GNOME on Fedora. Workstations + Hotkeys are amazing. I really dig the minimalism and compartmentalisation it offers.

I think i3 looks really pretty

Distro doesn't really matter nowadays. You can get all desktop environments to work on most distros. Especially the big players like KDE, Gnome, Xfce have hundred distros they are shipped with by default. Most big distros have versions for each of the most popular desktop environments. Therefore, I would suggest that you look for the distro which fits your needs best and then install the desktop environment you want to work with afterwards, if there isn't a flavor of your distro that ships with it already.

I've been using i3 for the past 8 years or so, and can wholeheartedly recommend it (or it's cousin Sway if you're in Wayland-land) if you're into tiling window managers (there are dozens of us!). I find them invaluable for their keyboard-centric operation, and also massively sweet on ultrawide monitors. Light on resources and minimalistic too.

As far as distributions go, I've been on Arch for the past several years. I think there are some (unofficial) spins for most Linux flavours with i3 out-of-the-box.

I used XFCE for a long long time before I went to tiles, which is a decent more traditional Window Manager, with a more lean focus than some of the others. Fairly customizable. I still use some of the system apps from there from old habit.

I wouldn't get too tied up into what window manager is default in any given distribution. At least for me, part of the joy is finding a combination of software (including the desktop environment/Window Manager) that works for you specifically. And there are plenty of live CDs (or usb images now I guess) with various WMs that can be used to take things out for a spin without commiting to installing it. :) Here are various Ubuntu flavors for instance.

Fedora or OpenSUSE with Gnome. Stable, GUI friendly, and simple.

I am into KDE Plasma, it works quite well on my distro (Fedora by the way) and one thing that I like about is is that I can make it truly mine. Defaults are nice, however sometimes I think I don't need that or need something else, and quite often I manage to do it to be the most comfortable for me. It's also very customisable and with enough learning you could rice it into quite a lot of stuff, even though I myself don't really know a lot how people do it.

Opensuse because of Yast; Yast does not have the best UI, but for some settings it's the only option if you don't want to use terminal.

I probably switch what I'm using every few months. The thing I cannot live without though is tiling support, whether just inherent to the window manager I'm using or an extension, I find it painful to use a computer for anything serious without one now.

Currently using KDE with the Bismuth extension (Fedora Kinoite) which isn't perfect but not bad. I'm eyeing Hyprland up from afar but as an Nvidia user I have too many issues on Wayland at the moment.

Fedora. It ships vanilla GNOME which is just a very pleasant experience. Vanilla GNOME is just something else man.

Nitrux, it's a Debian distro with KDE, a rather classic pair indeed, but their Maui Kit is what makes it really stand out IMO... Well worth a look 😁

I'm going to hop in here and suggest you try out Linux Mint. This is a distro designed for people who are coming over from Windows or Mac. It "just works". The UI doesn't throw away thrity years of convention simply to be "linux". Everything is exactly where you expect it to be and most of what you need is already installed.
Mint offers a choice of different desktop environments which are all laid out exactly the same, but have differing degrees of polish. If you're using a very old PC, you may want to choose XFCE because it is very lean, but lacks some of the nice graphical touches. Most people just use the Cinnamon desktop environment, which is highly customizable and polished.
I fully switched to Mint many years ago and never looked back.

All of them. Every distro can run any desktop, so all of them.
