Apple mastering the design of both the mobile and the OS, it is easier (if we can say that) to optimize the OS based on the characteristics of the mobile. Especially on android, many builders add their overlay more or less successful.
But the biggest problem of choice is mostly the ecosystem around it, accessories (with the more expensive apple-specific plugs), purchased apps, purchased movies that are sometimes hard to transfer from one to the other. For sms and contacts, we find now quite effective solutions, even if sometimes the import is sometimes strange (with an application I had tested, the first and last names were reversed).
But on the other hand, apple products are often more expensive from one generation to another, hard to follow, unless you sell the phone quickly, at least, before it loses too much value.
