The Linux and Windows kernels are equally stable
That is NOT true at all, unless you're working with the EXPERIMENTAL branch Linux kernels - then it's sometimes pretty close.
You can't be serious. The NT kernel has been rock solid since the 2003/XP days... and it was pretty darn good before then. The modern kernels in 2012/8.1 and 2016/10 run millions of production ready hyper-v VMs globally, so it absolutely has to be rock solid. I promise you, that Enterprises would not tolerate an OS that crashes as you make it out to be. Have you ever used Azure? Have you ever used 3D capable VDI instances with nvidia Grid technology? These are demanding and taxing use-cases, and customers would not tolerate instability.
This is not speculation, this is fact.
I'll also point out that NVidia and even more AMD put a TON more effort into their Windows drivers than they do into their LINUX drivers, which SHOULD make them more stable.
They also experiment with drivers a lot more on the Windows platform, trying to eek out as much performance as possible so that they can pass synthetic benchmarks for reviewers. Then they "fix" bugs in games and other video-intensive software by tweaking drivers to compensate for poor API usage by A-list gaming companies.
It's getting better for linux users, but they still get treated poorly by AMD and nvidia.
