You’ve named three great suggestions. There was a new stable Debian release two days ago. A decade ago, I found Debian stable a bit too stale and testing buggy, but things have changed for the better with flatpak being as ubiquitous as it is.

Just make sure to get the non-free firmware iso if you think you might need it for something like wifi.

I find snap on Ubuntu annoying, slow and the cli tool cryptic. I’d probably use PopOS in preference to Ubuntu just because of that.

Finally, the difference between using a Debian vs Fedora vs Arch derivative isn’t as much as it’s hyped up to be. It’s really the release cycle and QA that matter and that’s personal taste.

I’ve been pleasantly surprised by sway coming from dwm. It feels as responsive and most things I patched into dwm are built in.
