I switched from Android to iOS and back to Android because the keyboard typing predictions on iOS were so bad in comparison. It felt like I was using a phone from 10 years ago.
They also solve the issue for us using multiple languages on a daily basis (first and second mother tongue + English), without having to cycle through all the iOS built-in keyboards just because you want to mix in a few English words/phrases.
