Just to provide a counterpoint, I recently did a new desktop build and installed Windows 10. It's not bad, and very different from the Windows 10 beta that I gave up on in frustration two years ago. With the Ubuntu subsystem I can do useful work right away. After turning off some of the annoyances (via the Services and Group Policy control panels), it really does a decent job of just working. You can download and install with a USB stick (no more stupid DVDs). It still demands a license key, but runs indefinitely without registration with a little watermark.
If you haven't built a desktop in the past few years, the performance boost from PCIe NVMe SSDs is great, and Intel i5-7600K (now retails for $200) can run at 4.5 GHz reliably and stay cool. I'm impressed.
I came to a similar position recently. Bought a new laptop intending to run Ubuntu on it for personal development work. But the pet management story on the newer Intel CPUs just doesn't compare with Windows 10. WSL is pretty damned good and i don't feel so had using it. I'd objectively prefer to use Linux, but right now i just cant.
For me, I didn't notice much of a difference in performance. Ostensibly, the benchmarks say that it is ~5x faster, but on a day-to-day basis, I barely notice this - I rarely transfer files larger than ~10GB.
However, what I did appreciate was the (in-the-case) logistics difference of installing an M.2 drive; one screw, no cables, almost as easy as a RAM upgrade. Not having to fuss with SATA was a pleasure, and reminded me of the switch from IDE to SATA (you just... plug it in? Where are the jumpers?).
