So in essence, Apple's products are only world-class when you buy a lot of them so they can all work together. Taken by themselves they are not class-leading.
Let's break it down then.
Apple silicon gives MacBooks long battery life and great performance, while staying cool to the touch. On my MBA, I can zoom all day with it resting on my naked lap, without feeling any heat or discomfort coming from it. It also has a great build quality, great display, great keyboard, great trackpad (ie: it addresses all the essential fundamentals of what makes a great laptop). macOS also comes with a good amount of functionality out of the box, such as preview, iMovie, QuickTime and Notes.
My observation of windows laptops is that they tend to compromise in at least one or two of the aforementioned areas, not least because of the inherent limitations of intel / AMD processors. Till this day, I am not sure why Microsoft refuses to bundle a decent PDF management tool. On my work laptop (where I am not allowed to download third party apps), I have to either open a pdf in Edge in order to annotate on it, or in Adobe so I can view a pdf in two-page mode, and I can't perform basic pdf management like deleting or re-ordering pages.
I am also one of those users who genuinely prefer that the iPad does not run a desktop OS, at least for the things I do on it. So for me at least, this supposed "drawback" is actually a strength, and the iPad's key selling point. I have zero interest in my tablet becoming more of a traditional PC because that's what my iMac and my MBA are for.
I like AirPods because again, it does enough of the right stuff well enough. The case is small enough to fit inside the coin pouch in my jeans. It has good battery life, and I prefer earbuds because I wear glasses, and headphones would press the frame against my face. The stem of the AirPods make them easy to hold and handle, while they are comfortable enough for me to wear all day (and not feel a thing). Maybe each of these features by itself isn't "class-leading", but again, no one other product crams all these into one cohesive package for me. They all invariably compromise in one area or another, and that alone is enough to be a deal-breaker to make me not want to get one.
The strength of the Apple TV is that it is run by a company who, for now, has zero interest in try to serve me ads (looks at Roku) or sell my data (eg: pretty much every smart TV manufacturer out there). The integration with the apple ecosystem is also its key selling point, because if I use an iPhone, how else am I supposed to view my photos or listen to my podcasts on my TV?
Maybe what I have just said doesn't quite fit your definition of "class-leading", but my point is that I am using Apple products because they do tick all the right boxes for me, in a way that (I honestly don't think) the competition doesn't. Will Microsoft's new line of ARM laptops be able to run cool enough that I can rest them on my lap with zero discomfort? Maybe to the 99% of you, I am nitpicking. But it matters to me, and the beauty of it all is, the buyer is the end user and I don't really need to justify my purchase decisions to anyone but myself at the end of the day.
That's really where Apple shines, IMO. They can't go against the laws of physics, but they know where to make the right compromises (for me) so as the maximise the strengths while minimising the drawbacks of their products (again, for me).
Other competitors choose to focus on different bundles of pros and cons, which don't work for me. Perhaps it doesn't necessarily make them bad, but it's also why I probably don't see myself switching to them in the near foreseeable future. I just don't care for the product decisions they have made.
I am the quintessential Apple fanboy, and it's a badge of honour that I will gladly wear with pride. 😊
