GNOME gets a lot of hate for various reasons, but I really like it and don't really see myself giving it up anytime soon, I like it maybe a little too much... It looks pretty good out of the box, it has a really nice workflow once you get used to it, it has tons of extensions to change things you may not like or to add completely new things, it has a nice ecosystem of apps (GNOME Circle), and tons more. Though, I really dislike their decision of not wanting to support server-side decorations for clients, but it's a relatively small problem and it's whatever at the end of the day.
tldr: I use GNOME.
GNOME is the death metal of DEs to me in that I respect what they're doing and see why a lot of people like it, but it doesn't appeal to me at all.
I'm using stock Sway. It basically does nothing (you even have to install your own program launcher) but this fits my needs perfectly well. I'm comfortable configuring things using text files and the command line though.
I'm using KDE right now and never found a need to switch. It has all the modern features that you want in a DE (VRR, Wayland, modularity etc.)
Fedora Kinoite has been my daily driver for little more than 6 months now. I consider it the best Linux distro (personal hello hello seal of approval)
Back when I was at peak nerd and sitting in front of a computer all day everyday, I used Xmonad. These days I use KDE.
Edit: also in b4 hello_hello can reccomend COSMIC.
Just rocking with some old surplus minuteman systems, might fuck around and get a SCUD for the retro factor
Oh, I misread the title
KDE Plasma on my Optiplex Micro.
GNOME on my 10+ year old Macbook Pro.
Once they start theming qt apps we basically got ourselves a winner.
AwesomeWM.
Lack of Wayland support isn't much of an issue as I am stuck with nvidia graphics.
I like how there is a sane default config. In ~1.5 years of running it on my machine, I literally haven't touched the default config.
