I’m on arch currently (with an RX 7600 and R5 3600) and its a good experience, but I find myself wanting many of the .deb packages available on Debian, and trawling the AUR makes me nervous
would Debian testing give me a good gaming experience? I run all of my packages off of flatpak anyway, and would continue to do so on Debian
The AUR is a great option. I’d argue that it can often be a better experience than upstream deb packages, because there is more oversight to how it is packaged.
For example, lots of vendors will give you a binary “installer,” which kinda does whatever it wants to your system. Packages in the AUR often abstract this to simply a package with raw files.
Additionally, there may be problems with a deb, even on Debian. Instead of restoring to hacks, the AUR build scripts often include patches and fixes to get things to work, and it’s built right into the package.
I’m not saying that Arch and the AUR is always better, but the level of control you have over what you’re installing, and the visibility and quick feedback loop you get while fixing things is invaluable, in my opinion.
