I'm a complete Linux beginner preparing to move away from Windows. My main goals are to reduce my dependence on large corporations while still having a good gaming experience, especially with my Nvidia RTX 3070.
I'm considering CachyOS, Kubuntu, and Ultramarine. CachyOS appeals to me because it is Arch-based and tuned toward performance and gaming, but I'm concerned that Arch might be too difficult for a beginner. Kubuntu seems approachable because of Ubuntu's large community and extensive documentation, but I'm uneasy about Ubuntu's use of Snap packages and the way some packages may transition from APT to Snap. Ultramarine seems like a possible middle ground because it is Fedora-based and includes gaming-oriented tweaks, although I rarely see it discussed.
How difficult is Arch in practice, especially through something beginner-friendly like CachyOS? Are the rolling-release concerns justified? Is Ultramarine a sensible choice, and how does it compare with Fedora, Kubuntu, or Debian with KDE? I'd also appreciate clarification about how much the distribution itself matters for gaming, drivers, update policies, and desktop environments.

Debian with KDE is worth considering if you want a stable, well-documented system without Ubuntu’s extra ecosystem choices. Ubuntu is based on Debian, so much of the general knowledge transfers between them. It may not provide the newest packages immediately, but it is a dependable desktop foundation and should handle gaming through Steam and Proton reasonably well.
The biggest differences between distributions are their update model, support period, package management, desktop environment, and hardware support. App availability matters less now because many applications are distributed through Flatpak or other universal formats.
Arch uses a rolling release, so the system and desktop receive new versions continuously. Ubuntu and Debian generally use fixed releases, providing a more predictable base for a longer period, while Fedora sits somewhere between those approaches. Rolling releases aren’t automatically unstable, but they require you to pay more attention to updates and troubleshooting. CachyOS makes Arch much easier to install and use, but it still follows Arch’s general update model.
For gaming, any of these can work well with Steam, Proton, and an RTX 3070. KDE Plasma is a reasonable choice if you prefer a traditional desktop. Fedora or Kubuntu may be easier starting points, while CachyOS is fine if you’re comfortable learning as you go. You can always switch distributions later.
That helps clarify the real trade-off: it sounds less like Arch is impossible and more like it expects you to take responsibility for updates and troubleshooting.
CachyOS with KDE Plasma is a reasonable beginner-friendly Arch option. Its installer and defaults remove much of the difficult installation work, and you get current software and gaming-focused tweaks. The reason people call Arch a hobby is that you may occasionally need to read update notices, consult documentation, or fix something after a major change. That doesn’t mean it breaks constantly, but it is less hands-off than a long-term-support distribution.
Ultramarine can also be good, but check which edition you are installing and whether it is an immutable or atomic variant. Those systems are designed to keep the core operating system unchanged and commonly rely on Flatpaks, which improves reliability but can make deeper system customization less convenient. If you want maximum flexibility while learning, a conventional Fedora, Debian, Kubuntu, or CachyOS installation may be simpler.
I hadn’t realized the specific Ultramarine edition could affect how much of the base system I’m able to change. That makes CachyOS or regular Fedora seem more appealing for a first install.
Fedora is also a strong option. It is modern without being a full rolling release, and its defaults are polished. Ubuntu is not secretly installing packages in the sense of hiding the change; when an Ubuntu package is replaced by a Snap, the package manager generally tells you. Whether you like Snap’s design is a separate question, but it doesn’t have to be a deal-breaker.
For someone who wants a straightforward first installation, Fedora KDE, Kubuntu, or Debian with KDE would all be sensible. Nvidia support is usually manageable on current releases, and your RTX 3070 is old enough that drivers should be well supported across the major distributions.
I’m still wary of Snap because of its centralized and partly proprietary ecosystem, but it sounds like the practical impact is smaller than I initially thought.
If you were already leaning toward Kubuntu, Debian gives you a similar KDE experience with a more conservative update policy and fewer Ubuntu-specific decisions.
