I run Linux on a small mini pc for some casual browsing.
I run windows on my main pc.
As long as some kernel anticheat (fortnite, cod, etc...) doesn't run on Linux, I won't be swapping.
30+y of windows use also makes me infinitely more comfortable with windows. All the complaints I always read about are totally moot for me (I understand the issue of privacy in windows. It's the price I pay to have an OS that "just works" for me) .
While I enjoy tinkering, Linux is a royal PITA to use if you're not used to it. I spend hours trying to figure out how to fix something that takes me 5m max in windows. I understand it's a more a me than a Linux problem. But I'm certain many people struggle with the same things.
I use popOS. Windows is still simpler
