For the record, I'm very familiar with most of the OSs you mentioned: Windows, Linux, MacOS, and Android (on a variety of devices). And I think the only fair statement is that they each have unique strengths and weaknesses. You can worship MacOS to high heavens, but it is also lacking in many ways and owning a MacBook comes with numerous downsides (as well as upsides), compared to a Windows laptop.

The only OS I don't have much experience with is iOS. I've stayed with Android the whole time - largely with Samsung. A high end Samsung phone is an absolute powerhouse, while also looking pretty sleek, if I may say so. I personally think that iOS and iPhones are quite limiting in certain ways. But I would never knock on someone for using iOS. The OS and the phone look very nice and trendy, the whole experience is very well optimized and, at least in the U.S., you'll get certain social perks by having one. Even for older folks, it could be a great choice, because their grandkids will be able to fix most problems that could arise in their phones.

Let me revisit a prior point about iPhones - they're not very customizable. On my Samsung, I have a number of customizations: a custom "launcher" ("Nova"), which enables me to tweak things like icon sizes, density, and many many other things (my favorite feature is to use a custom icon set). I could easily keep naming countless other aspects that Android allows me to customize, even if I only customize a few of them. The default experience of a Samsung phone is quite solid, other than maybe having a few too many Samsung-specific apps pre-installed (though at least I never buy through a carrier, so I don't have to worry about any of that bloat). But it's very trivial to nerf them by disabling them or even simply uninstalling them using "pm-uninstall" through ADB. For me, it takes maybe 20 minutes total to apply various tweaks I like to a brand new phone. I have them all written down neatly and they haven't changed much for a while, so applying those customizations is not bother for me at all. But for others? It would be an unimaginable punishment. Many people prefer to buy an iPhone not only for all the benefits I listed out earlier, but also because it is more restrictive. Because of this, you don't have to deal with any of the 'pain' of trying to decide what should be customized and whether you should do so in the first place. But would I judge anyone for taking either route: 1) a Samsung that you customize to a reasonable extent - without rooting or unlocking the bootloader - vs 2) an iPhone that is effectively at stock settings, other than the apps you've downloaded? No, I absolutely would not. Which brings me to my last point..

I think we live in amazing times in terms of technology (aside from the obvious issues related to privacy and social media, which are discussed at great lengths here and elsewhere). We have many choices in terms of hardware and software and our devices can do things we could hardly fathom a few decades ago. I rather arbitrarily chose to focus on smart phones in my rant, but I could have easily discussed laptops, desktops, servers, or some other type of device to make the same point. So I say, "Live and let live."
