I use EndeavourOS (which is arch).
Most of my programming is web stuff. So it builds to containers and using VS Codes dev containers takes care of all issues relating to arch's rolling release (IE needing a specific version of a language).
Ie, I work in containers and I build to container and I run containers for all my code (except ESP32 platformio. Unfortunately I haven't migrated that away from windows. So I dual boot)
If I was doing GUI desktop apps, I imagine I would need something other than dev containers.
But that's not what I do.
Considering all I do is docker, k8s, linux admin, web frontend/backend that is platform agnostic (but ultimately runs on Linux)... I'm not tied to any OS.
Windows is annoying, I am not a fan of osx nor Apple, I use Linux everyday... So my OS might as well be Linux.
And Arch & EndeavourOS are nice and just work.
For a VPS/server, I use Debian (or Talos OS for k8s). But that's all headless.
I'm lucky in that I freelance and the companies I work for are good companies.
I've never had to cancel anything because of EndeavourOS, it's never broken on me (I've only had windows break the EFI partition, which it can do to any distro - until you disable fast boot and stuff), it's never gotten in my way (or if it has, it's lead to a better solution - like VS Code dev containers). It's been really really enjoyable.
I'm sure that I could use any distro in my position, tbh.
So, probably not helpful overall.
Yeh, KDE plasma
