It could be mostly steamdeck users, but for me arch is the only distro that works well. You know what you install which makes troubleshooting easy, and it's documented very well.

It's only that high because SteamOS is built on it.

I don't mind but for a desktop I definitely prefer Nobara, I've had no issues installing it getting games running on multiple devices with it.

It's a very good distro but for some weird reason, the general attitude is that it's only used by unpleasant people who want to tell everyone they are a hacker.

It's a really, really good distro with excellent wiki. It's for anyone who want to learn about linux. Takes effort in the beginning but it's so rewarding.
