If you use a distro based on Ubuntu or Debian (like PopOS and others) I recommend Regolith Desktop. You can install it on an existing setup and it’s ready to go out of the box. You can choose it from the login screen like any other desktop environment like GNOME or KDE. The next version will also bring Sway/Wayland support since obviously X is on its way out in the long term.
It’s been rock solid for me going on 3 years now. I started using pop 20.04 and then upgraded to 22.04 and upgraded my DE from Regolith 1.6 to 2.0 and despite all those rather large major version leaps, I’ve had no issues.
And I’m a remote developer (doing LXC and other systems level development) using this on my work laptop that has to stay functional for my livelihood, so stability is paramount, but also the ability to customize things without it breaking the world.
If I didn’t have a System76 laptop with a dGPU I might just use Ubuntu or Debian because I don’t really utilize most of the pop-specific features (e.g it’s tiling functionality) aside from from the ease of dealing with power management and Nvidia graphics, but it’s still a great distro.
