I don't know the current status, but iOS's design meant apps at least used to be _far_ more efficient than the equivalent Android, and thus Apple could ship lower end hardware to deliver the same or better performance to the end user. The was a measurable fact, thus objective.

The same is still somewhat true for macOS where for the average web browsing user, macOS + Safari needs less memory than you would need on Windows. This is also a fact, but it doesn't help power users.
