I don't think either is better than the other, just a different way of using the same thing, a smartphone. Personally I prefer to use the iPhone because I'm familiar with it and it suits my needs very well. My business phone is an Android and it suits my business needs very well however the iPhone can meet those needs too but the Android is generally cheaper and has access to many 3rd party apps that won't be available on iOS.
I will say that those that defend Android phones that have way more power and memory than iPhones, there is a reason for that. Because Android is written in Javascript, it takes more processing power and memory to run it, however it does performs those tasks very well, you have to realise that Android works on a wide spectrum of devices (except Huawei, lol), so there are deviations in terms of hardware and technological limitations.
There is no point saying iPhone is better or Android is better, just choose which suits you and be happy with it. At the end of the day, there is always someone spying on you, either the Chinese, Russians or Zuckerberg.
