Windows is, quite undeniably, sluggish.
Indexing is way more read intensive than it should be, some things just take forever to appear and killing a process/task seldom works on the first try.
Even Microsoft kernel devs themselves admit that they're somewhat behind other operating systems.
The Windows NT kernel is really progressing at a snails pace, compared to Apple's XNU, the Linux kernel and BSD.
Work outside the kernel isn't any better either. One literally can't go through the day without reading news on GNU/Linux or one of the BSDs. The same cannot be said about Windows.
Weren't people buying apple intel laptops and installing Windows because it was really fast hardware but MacOS ran slower than Windows?
Actually, people are buying Apple hardware because it's the most compatible (i. e. they don't need to manually install as many drivers).
As far as performance is concerned. That's actually quite a bit of a myth. The agency publishing those performance benchmarks later admitted that they compared a clean slate Windows installation on the Macbook to HP/Toshiba laptops running all the pre-installed bloatware.
In hindsight, earlier (pre-2013) models could actually perform worse under Windows, since they all rely on an earlier version of Bootcamp that didn't support EFI natively, thus relying on HDD performance inhibiting Bios emulation. AFAIK, the Macbook Air 2013 was the first one to include an UEFI 2.0 compliant boot loader that could boot into UEFI Windows natively.
