Valve amended the Steam survey for December 2025 - Linux actually hit another all-time high
(www.gamingonlinux.com)
I've installed Windows on thousands of machines and IMO, major Linux distros are usually easier to set up for home use but I say that having used both for a good amount of time, so my opinion is definitely biased compared to someone who doesn't really use computers.
I would argue though, where Linux really shines is old systems, much like the many that MS chose to drop support for in Windows 11. There's a pretty decent chance that the bullshit going on with RAM and drives might actually further drive Linux adoption as people try to get more out of their existing machines or old used\refurbished machines that they can actually afford (which Linux runs great on, unlike Windows).
Time will tell though...
