If we are talking about desktop PCs, maybe Ubuntu, but based these reports it’s Arch.
That’s because SteamOS, the operating system preinstalled on the Steam Deck, is based on Arch.
I don’t understand why they haven’t offered a way to filter out the Deck from those results. It skews every category (CPU, GPU etc.)
Worth keeping in mind that the steam deck uses a distro based on arch, so it might be inflating the arch numbers in that steam survey.
I don’t think it is. Mint is based on Ubuntu but still shows up as mint. Arch is very popular
With Steam having a gaming audience I’d argue that this has at least a slight bias towards Arch, as the latest kernel versions and other software are often advantageous for gaming in particular.
But even with the Steam numbers note that Arch is just listed as one single variant, while Ubuntu has separate entries for different versions. Ubuntu LTS 22.04 alone is so close to Arch that it’s probably ahead once you include all versions.
