The upgrade process on Kinoite (KDE Atomic) was extremely fast and smooth. Fedora has always been among the most reliable when it comes to upgrades in my experience.

Voyager is definitely the most polished and great for those who used Apollo for Reddit. It is also very actively developed. For the Android users who do not mind the iOS aesthetic, Voyager is one of the few Lemmy clients on F-Droid.

Thunder is also a great option. I personally prefer its UX more than Voyager, but it is not quite as polished.

But T-Mobile is still offering the service, so it is not the lifetime of that either.

A GitHub issue was opened for Syncthing-Fork, so it will be worth watching that to know whether it will continue to be supported.

openSUSE also remains one of the only distributions that have automatic Btrfs snapshots setup out of the box. I am very surprised other distributions have not done the same. Especially Fedora, since they use Btrfs already.
