I've been using Arch as a daily driver for years and love it's customization level, then I realized I just want an OS that works. I need tips, advice, or even warnings before moving.
I used the "normal" Fedora (Workstation and KDE spin) for years and now moved to the Atomic variants.
Especially uBlue is fucking great, as it is just the default Fedora Atomic with some tweaks and QoL-changes.
It basically "just works" ootb and maintains itself.
You can take a look at Bazzite if you're into gaming for example.
It's also very customisable, but you have to learn a different approach.
I personally would give it a chance if I were you, but beware, you have to learn a new workflow
You don't install software to the host directly, but with containers, e.g. Distrobox or Flatpak
You can still install packages directly if really needed (e.g. drivers), but it is largely not recommended
I personally strongly prefer Atomic to the mutable version, but that's my taste. If you prefer the traditional variant, then go for it. In that case, you don't need to know anything particular, it's nothing special :)
The cool thing is: you can rebase to any other Fedora Atomic variant if you want with one single command, which feels like a clean reinstall, but you keep your settings and data.
Pretty neat if you want to get the newest rolling release feature from rawhide, then rebase to KDE and then an Ubuntu clone.
You can also make your own images from skratch with the uBlue builder :)
