Fedora, it fucking slaps and worked right out of the box. I’m using it for work and play on my main rig! I dual boot for some very specific hardware things that are not normal, but other than that it’s been seamless! When I booted into Windows 10 again, they auto installed copilot… Glad to be done with this crap.
For file synchronization (not backup, at least not without a bunch more steps) I use SyncThing. It’s local, and can be configured to not connect or communicate with any remote service. It keeps a directory on my laptop and desktop in sync whenever they come into the same network.
I knew there was a big one I was forgetting! Never used it but hear good things all the time
I use syncthing to sync files between devices. But I also like to store less uswd files (along with the rest) in the cloud.
