Yes and no, my main system is EndeavourOS as well as one laptop that stays docked in the bedroom as a media PC. My HTPC is running Mint with KDE, my Steam Deck is stock SteamOS, my MacBook Pro is running Asahi Linux, server running TrueNAS and Raspberry Pi’s running stock Raspberry Pi OS. Mainly I just like KDE, and have a preference for Arch based systems.

I prefer EndeavourOS and haven’t had issues with it for a couple years now, but Mint on the HTPC was a reason to try Mint and I just left it alone except for swapping Cinnamon for KDE. Asahi is the only option for M1 MacBooks so no choice there. Pi OS I never really use the system as a computer, I just have one running PiHole and another running a digital calander for the wife and I, so I only interact with them through ssh or web portals. My Steam Deck works perfectly fine as is and I mainly just use the Steam launcher anyway so no point changing it. The TrueNAS system I mainly use through a web portal or SMB so it’s fine.

Usually I keep everything on Debian, but I’ve been thinking in making some changes, like running mint on my kids laptops. My rock64 is running armbian, due some problems with latest Debian on it and DietPi on an rpi3. Oh yeah, an rpi4 is running has, due to my absolutely laziness 😂

I use the following

Debian for Laptop Bazzite for Gaming PC HatvesterHCI for Hypervisor Truenas Scale for NAS (VM with disk pass thru) Rocky Linux for Servers (I have created Hardened Images) I use OS-build to create the Rocky Images

Fedora just works for me in every case except NAS where I have TrueNAS, so Fedora it is and I installed it even to couple of people and they also like it.

I feel like NixOS might be the only distro that could realistically handle all these use cases, but I’m a bit scared of the learning curve and the maintenance work it’d take to migrate everything over.

It’s a very steep learning curve, but I personally think it is worth it if what you want is to sync up all your various devices to a single common baseline configuration. I sought a single-distro solution for all of my systems for a long time and always ended up fragmenting them eventually because nothing I tried until NixOS was capable of handling such a diverse set of use cases in a way that would satisfy me.

I am similar to you, in that I regularly use a three server cluster, a gaming desktop, a multi-purpose personal laptop, and a work WSL instance on my work laptop. I still have some purpose-built distros where it makes sense; I use Proxmox for the actual server hosts themselves and then run NixOS VMs on them, along with running VMs for Home Assistant OS and TrueNAS (with the drives passed through, of course). All of these things I could do on raw NixOS (even Home Assistant is packaged in Nix, and there is a project to port Proxmox UI and tooling to NixOS) but I like the stability of the dedicated and battle-tested distros for critical infrastructure, especially for stuff whose configuration is very specific to a given task.

With NixOS, each other device has a consistent shared configuration and package set, they all get updated to the exact same versions thanks to flakes so everything works the same and as expected no matter where I am, and it’s all declaratively configured and documented in one spot. Spinning up a new system or rebuilding an existing system is as easy as pulling the config and changing a few relevant lines, and from there it effectively assembles itself from scratch to the exact state I want it to be in. There’s never any lingering packages or configuration cruft because the system is assembled from scratch every time it updates. Much of my home configuration is also managed, so aliases, environment variables, even vim configs are consistent across the board and set in one location.

The main downside is resource efficiency. Nix is designed to be reproducible and declarative, not fast or lean. It uses much more storage than a typical package manager, and packages are built with wide compatibility in mind so you often are leaving performance on the table from not using newer instruction sets like CachyOS. You can compile your own packages to fix that part, but that obviously takes a lot of spare processing power. I’ve been considering setting up my server cluster to do automatic building for me, but haven’t gotten around to it yet.

Nah. Debian for servers, Fedora for desktops and Arch for funtimes.

Slackware on desktop, laptop and mini PC, Debian on anything smaller

Workstation: Fedora plasma Server: Ubuntu Rock64 Libreelec

Fedora on laptop. Fedora on desktop. Fedora in the server. Fedora in WSL.

I use NixOS on everything ! This way, I can re-use parts of my configuration as a base, and customise only the few things that need to change from one machine to the other.

The only exception is my Steam Deck. I trust Valve on that one, and my usage of it is so different from other computers as to make 95% of my config entirely irrelevant anyway.

Kind of.

Fedora on workstations. Debian on servers

No, Arch for laptops/desktops. Debian for servers.

My home server is on unraid while my other machines are on OpenSuse. Having a webui makes it so much easier for someone other than me to take care of stuff if I’m not around

Yes
