I'm guessing you have a very positive experience with gaming PCs; I wish I could say the same. My Windows PC:
- Randomly BSODs because of (I think) a buggy Focusrite audio interface driver (that I can't fix and Focusrite refuses to)
- Regularly 'forgets' I have an RX 5600 XT GPU and defaults to the integrated graphics, forcing me to go into the 1995 'Device Manager' to reset it
- Occasionally just... stops playing audio?
- Occasionally has its icons disappear from the taskbar
- Regularly refuses to close applications, making me go into the Task Manager to force-quit them.
These are just the issues I can think of off the top of my head. I've been playing PC games for like 15 years and this is just par for the course for my experience.
Definitely an outlier. Windows has generally been very very solid since about Windows 7. Certainly since Windows 10.
Linux is still quite far behind in terms of desktop stability in my experience. But I guess if Valve fully controls the hardware they can avoid janky driver issues (it sounds like suspend will work reliably!), so this might actually make a good desktop Linux option.
You are also definitely an outlier. In my experience, Linux has been 5x as stable as Windows (and more performant, too). SteamOS is just Arch Linux with the KDE desktop, the actual desktop stability wont be different from the same setup on a normal PC.
I also had frequent BSOD issues because of a Focusrite audio interface, lol. I've since thrown it out and gotten an alternative brand product and have never had the issues again.
