I thought I already explained this. OS isn't the sole, maybe not even the main arbiter of performance when compiler and developer biases can cause a greater difference. I already explained that some scenarios (like FS) would have significant variance due to the differences in design philosophies. That doesn't have to mean that one OS is objectively worse than the other, but it could mean that they prioritize different scenarios. I don't think we have any way to tell if an OS is objectively "faster" without resorting to micro benchmarks which you're right about them not being so meaningful.
