You don't have problems with Arch presumably because you've avoided building your system into a neutron star of corporate shitware, while that's the default state for most distributions.
I'm not blaming anything on the kernel (other than memory management). The userland ecosystem is part of what makes an OS, a perfect kernel with no userland is of no value to the general populace. You don't really get to discount everyone's complaints about the Linux experience because they aren't complaints about the kernel, or at least you won't convince anyone by doing so. It is clearly possible to solve many of the issues I have on top of the Linux kernel, because Android used to be decent, but it seems the desktop ecosystem is just locked in to too many bad choices at this point.
The vast majority of complaints about Windows have nothing to do with the NT kernel, either, which by most accounts is actually quite good.
This is one of the points where people have vastly different experiences. I'm one of those that has fewer issues with Linux, and I definitely don't spend hours fixing problems. And this despite the fact that I use Arch, which is supposed to be an unstable distro. Why is that different users report so different experiences I don't know. I think that this might be partly due to perception: we tend to forgive more the OS we like. But your case doesn't seem to be just about perception. So I wonder how much the hardware could play a role here. I think Linux has quite good hardware support nowadays, but maybe I was just lucky so far.
