And I did not say that I chose Arch-based for the nvidia driver, but for the more up-to-date drivers.
But that's what I mean... It's not to do with being arch-based, but what the distribution chooses to ship. Bazzite is Fedora based and also ships with the almost-newest proprietary nvidia drivers.
For the record, I don't have an opinion on your choice of distro, use what works for you. I just see so commonly from arch users that they have access to the latest drivers, but that is true of anything running a recent Linux kernel. I was just wondering what about arch makes this belief so strong.
