I am not a religion follower in any thinkable way
But a happy user, for sure. The issue is, that any positive or negative experience report from any side is easily perceived as preaching and evangelizing. That's not my intention. Still, I have spent a lot of my life time typing on keyboards and staring at screens connected to computers running all kinds of systems (CP/M, DOS, Windows, OS/2, BSD, Linux, Irix, HP-UX, Solaris, Novell Netware, macOS,...) and made decisions for myself based on all these experiences for good reasons. Just as anyone else. It's a personal decision that everyone needs to make and I see no religion in sharing the reasons behind it. The issue that arises quite often is that people consider their own personal decisions as "right or wrong" kind of decisions and expect everyone else to have the same priorities.
My experience with both sides is similar to JoJu's. When using windows, I spent a considerable amount of time on upgrading all kinds of things, both software and hardware. In fact, I spent at least the same amount of time on keeping my system up to date, so working on it than actually working with it.
For me, the Mac, as they said in ads back then, "just works". I don't worry about upgrades much anymore and can focus on work that needs to be done. And the level of support from Apple is unmatched when it comes to keeping things alive for quite a while. True, my 2008 Mac Pro is officially no longer supported (it takes an external patch to make it run High Sierra), but even given its regular life cycle, which ended just last year with the introduction of Sierra, that's an enormous time frame.
We had to abandon much younger workstations at the office, that were sold with (and still running) Windows 7, because there was no upgrade path to Windows 10 on these machines (not cheap no-name machines, it was HP ThinkStations, so similarly expensive stuff).
For me, there are so many things on the Mac (or the iPhone) that reliably work, but are a major headache on Windows (or Android). A simple but reliable backup and restore is just one of them, but to me of such importance that I never want to miss it again.
Talking about security: there are barely any current threats, but there are some. For a typical private user, those threats are nothing to worry about, IMO, if you keep your system up to date (which it usually does by itself). I don't run any security software other than what comes with the OS and "Little Snitch" on top since I have a Mac (so for for a little more than a decade now). If you're paranoid, trough, (and if you're admin of a large company network, you're obliged to be), there is no way around security software, because a single instance of the smalles malware slipping through causes loads of work and costs huge amounts of money.
