I’ve had a bit of a look into Tumbleweed and it sounds like it’s similar to Fedora in how it handles packaging of proprietary software which I found pretty annoying, but I could be wrong.
It’s true that Arch is leaner towards proprietary software if that’s what you mean. An example of this is how the Nvidia drivers are just found within repos for Arch (thus enabled by default), while on both Fedora and openSUSE it’s not found in the official repos. Both have made it easier over the years to somehow include options and whatnot within the installer to ease Nvidia users in, but the experience on Arch is definitely smoother.
Furthermore, Fedora is indeed (kinda) hardcore on FOSS, similarly to Debian. While Arch simply doesn’t care in most cases. My relatively short endeavor to find out where openSUSE fits in seems to point towards openSUSE leaning closer to Debian and Fedora.
What’s perhaps important to note is that in all cases there are third party repos that can easily be enabled to acquire proprietary software.





A couple of assumptions I will be making:
Typically, distros like Arch, Debian, Fedora, Linux Mint, openSUSE, Pop!_OS and Ubuntu (or their derivatives) will be mentioned in these kinds of queries. And it becomes mostly a popularity poll that measures what the community thinks is the preferred distro for beginners. And honestly, I don’t blame them as you haven’t really given us a lot to work with. My entry to that popularity poll would be Linux Mint. If you prefer to use GNOME or KDE Plasma instead, then consider either Fedora or openSUSE Tumbleweed. Additionally, Pop!_OS should be considered if Nvidia causes problems on all the others.
Feel free to inquire if you so desire!
EDIT: I just noticed how you mentioned to someone that your use case will be primarily gaming. First of all, gaming is somewhat equal on most distros; especially with the likes of Bazzite-Arch and Conty providing excellent environments for gaming regardless of installed distro. Though, these containers do still rely on the hosts kernel, therefore any perceived difference on same hardware but different kernels might be attributed to said kernels. Newer kernels generally come with improved performance; at least for newer hardware*. Though, perhaps more performance could be gained through other means as well. I will spare you the details, however, as this is potentially another rabbit hole within the initial rabbit hole. Therefore, instead, I will name a couple of distros known for being excellent for gaming purposes: Bazzite, Garuda Linux, Nobara Linux, PikaOS and RegataOS. If you want a no-nonsense system, just go for Bazzite; while initial setup might seem slightly more involved, it’s by far the most robust system out of these. This does come at the cost of being ‘unique’ amongst the others, but I believe it’s a great fit for your use case.
