Ah yes. The ancient ios vs android debate.
They each have their use cases, and I can understand the justification for using either.
My specific threat model (similar to high profile journalist covering topics that expose wrongdoings in high positions of power) has me using iOS, where the cons of being locked in Apple’s walled garden don’t outweigh the benefits of having a robust, secure operating system right out of the box without much setup and maintenance (i.e. Lockdown Mode).
Other folks’ threat models have android on the winning side. It is highly personal, and making grand statements about one being better over the other is childish.
The only other option that I see as more viable is GrapheneOS on a Google Pixel, but I have yet to make the leap. Maybe soon.
