From what I understand, the KDE team used to use OpenSUSE as their distro of choice when testing KDE. This has changed now to KDE Neon being the flagship KDE experience. Also OpenSUSE will install Nvidia Drivers during install if you select that option. You’ll have to enable the Nvidia repo later on too. But it’s dead simple. Definitely give OpenSUSE a try. I’ve been using for a few months now on my laptop and it’s fantastic. It just works, including BTRFS snapshotting, right out of the box.
I would say the benefit of OpenSUSE is that everything is preconfigured to work right out of the box, including btrfs snapshotting with snapper. Once you boot it’s time to download apps, and go. Very windows like for those who just want the system to work. Updates are one click.
