Linux the kernel is fundamentally inferior to NT from 30 years ago, Linux the userspace is barely tolerable, Linux as an ecosystem is an amateur clownshow barely held together by corporate donations of drivers and absolute dedication of a handful of volunteers of wildly differing skill.
If your biggest innovation of a decade is a carbon copy of a feature introduced in NT 3.5 in 1994 AND THEN it turns out most serious people disable it because you cannot even copy a feature without introducing new vulnerabilities - that's a sign of quality.
NT was originally designed along the lines of a microkernel though in NT 4 they violated the rules and put the graphics driver in ring 0 (iirc) and didn't undo that until around Vista, I believe.
Technology-wise, Windows NT and it's APIs is well developed and designed.
