Even though different Linux distros are often fairly close in terms of real-life performance and all of them have a clear advantage over Windows in many use cases, we can't reject the fact that Arch Linux has undoubtedly won the competition.

I think it depends on kernel/software/driver versions and will vary when these change. Also bloatware is a thing, even though it doesn't affect the results very significantly
