Considering I have a MacBook Pro, 3 AppleTV’s it only makes sense for me to prefer iPhones. Everyone in my family has an iPhone. I have an iPhone XS Max, my wife has an iPhone 11 Pro, my brother in law has an iPhone XR, my mother in law has an iPhone 6s+ and my father in law has an iPhone 7. It’s what we are used to and what we like.
I have used Android devices in the past and while they are nice the whole Apple ecosystem is why I like their products.
