But your guess as is good as mine as to what those reasons are. 😕
The reasons are hard to see because the question appears to be about technology. The questions are about people.
People like having choices, they like making choices, and most importantly, they like feeling good about those choices. You make a choice and someone comes along and says you you made a bad choice, that's a challenge. A challenge to your abilities and judgement, a challenge to your worth.
A variety of products serve a social function. You role up in a Bentley, there's a message. People seeing that message who can't afford the same car may feel inferior (or made to feel inferior). Someone roles is with their apple device knows they paid more and knows you laid less for your x, y, or z device. To avoid that same inferiority, it's important for your device to be better than apple's device.
Depends how you measure. If you look at spec sheet, sure there are more powerful options out there.
If you measure by things like seamless sync with other devices, automatic backup, security, update longevity, after-sales support and a host of other non-spec-sheet metrics, then subjectively, it offers a better experience.
This is the actual technical difference but it too is not - really. Most companies in the world start with a list of features. They figure out what you want it to do (usually as many things as possible), then figure out some kind of container to hold it all. This is a philosophy.
Apple starts with a design. The design is specific and considered. Into this design are screened a list of prospective features. Only those deemed worthy are granted admission and make it into the finished product. This is a philosophy as well.
Neither philosophy is 'correct', they're just different. Those who see value in features per dollar can pick one. Those who see value in design, can pick the other. This difference shouldn't make others feel bad but it does. But only because they already do.
