I see this sentiment a lot but the developer experience on Windows is good to great in my experience.
Much better than MacOS or linux if you are using Visual Studio and .NET, pretty equal if you are using another stack.
What it isn't is posix/unix. A lot of the bad developer experience people have on windows is from trying to (pre-WSL, at least) shoe horn unix tools and practices instead of doing things the windows way.
Writing Windows software, I’m sure, is easier on Windows.
Happily Valve fixed the whole gaming issue, outside of niche DRM stuff that I don’t care about.
This site shows how well games run on proton and people offer solutions to get them running if there's any snags.
Boy is it bad! Consumer versions of Windows are basically malware at this point. No idea how people can get stuff done at all.
