No, they aren't. The S25 Ultra is more expensive than the 17 Pro Max; sale discounts notwithstanding. And Android is not that much more open and customizable than iOS at this point; in fact, since Android 9, Google has been actively locking down more aspects of the operating system. The only things Android have above iOS at this point is icon packs and custom launchers (and in some cases, the ability to set a custom system font); features that the vast majority of Android users don't even use. Aside from those features, iOS is on a level playing field with Android at this point, and in some cases even goes above Android. And sure, Android is open source, but 99% of the population don't care about that. The biggest reason people go the Android route is because its all they can afford, especially in developing countries and countries with lower incomes per person compared to the western world; hence the popularity of WhatsApp in those countries.
You're entitled to your opinion of course, but saying Android is more open and customizable is just disingenious and mostly untrue at this point.
