@SecondHandStoke This is pretty much why I feel there can be no absolute best, only what is best for you.
Apple does pay close attention to aesthetics, but tend to get a lot of their back-end stuff from elsewhere; enough so that I won’t give Apple as much credit as others would. Without Xerox PARC, there would be no Mac, and without BSD, there would be no OS X. Apple really hasn’t invented much, only marketed it better than who they got the ideas from, then secured the patents/copyrights on it.
Also, I separate the UI from the OS. What many consider the greatest strength of Apple is actually the Aqua interface, and I will concede that they did a decent job there. But I still prefer Cinnamon (a fork of GNOME) over Aqua though, and if I did want Aqua, I could get it for any Linux distro. See, the interface is just a module; it is not the actual OS itself. You can make the UI look however you want without affecting the underlying architecture of the OS just as putting on clothes and/or makeup won’t change your personality.
Regarding design quality, I place function over form, and am not a fan of the high profit margins involved in artistic design when shopping for something that I actually plan to use rather than just look at. I’m not paying twice the price for a pretty computer that is actually no more reliable than it’s competition (Lenovo and Asus are in the same ballpark, and the latest numbers I’ve seen show Samsung far ahead of Apple in reliability), cannot be worked on easily, or otherwise will fall far short of meeting my needs. Sure, they are pretty to look at, but if I wanted art, I would shop at an art studio instead of a computer store. Looks do matter to me, but not enough to pay double; the price difference alone is more than I paid for my car. They aren’t bad at design, but they design their products in ways that actually eliminate some of the things I would accentuate, like ease of access.
Also, I have seen that level of quality and attention to detail on the Linux/Android side of things; it’s just not as universal simply because, unlike OS X/iOS, more than one organization develops for Linux/Android, and you will find more variance in a group than you will in an individual.
Still, that is me, and you are free to choose different products than I would. At the end of the day, it’s really about what the person spending the money wants, and as our tastes our different, so are our purchasing decisions.
