Next, my personal perspective from having used Macs since the beginning — 1984, and from having used the first "desktop" computers before then: CP/M machines from companies long forgotten, the TRS-80, Atari, Commodore, the original IBM PC, and even longer ago, DEC and IBM mainframes... ancient history. You can scroll down to my next reply if you want to omit the commentary.
For years, even decades, Windows users have become inured to doing things a certain way. I'll call it "the Microsoft way". If you're one of them, you will not be happy with a Mac. Not at first anyway, not until you un-learn most if not all of what you know. The original Macintosh design represented a radical departure from everything that came before it. My personal perspective at the time was that it was what a personal computer ought to be, and its future trajectory was obvious. Everything else would be left to the ash heap of computing history.
About ten years later Microsoft came up with an operating system for the IBM PC that superficially resembled the Mac's operating system. At the time my reaction was wow, this looks just like a Mac. It took about five minutes for me to conclude Windows was a visual facade built on the house of cards that was the original IBM PC-DOS which itself was inferior to even the CP/M operating system that came a decade before. The reasons for that are a subject all to itself which I won't get into here.
In any event Microsoft spent at least another decade to catch up to what the Macintosh already had been for a long time. Meanwhile, Apple realized the original Macintosh operating system was never going to evolve to future computing needs and requirements, and they took the bold step of abandoning it altogether in favor of OS X which later evolved to become macOS we have today. All the while, Mac hardware was changing on a fundamental level. Macs are now up to the fourth major clean-sheet hardware design in Apple's own proprietary chip hardware: first there was the Motorola 68000, then the PowerPC, then Intel, and now Apple M series chips. No one uses them but Apple. It's a completely closed system, as far as hardware is concerned. Due to their enormous installed base, and thereby lacking the same agility to innovate, Microsoft has remained locked into Intel (or Intel-like) hardware.
Yet Microsoft made great strides into improving their Windows operating system. It's much more secure than the practical joke that it had been, which at the time led to a cottage industry of "anti-virus" product peddlers. That cottage industry is now a multi-billion dollar behemoth, and it will not permit itself to be ignored. They have successfully convinced neophyte Mac users that macOS is just as vulnerable to "viruses" as PCs. This is a lie. It always has been, but if not for deception and half-truths we wouldn't have marketing majors at all. Lies make the world go 'round.
