I am an Android developer (and user) with 14 years of professional experience, and I put my elderly mother on iPhone many years ago.
For me it came simply down to the simplicity of the iOS system. There are fewer clicks, buttons and functions for her to accidentally get into.
Another reason is also that my other siblings (and all of the grandchildren ) are all on iPhone, so I am not a her only IT support person in case one was needed ASAP when I would be unavailable.
Personally I don't enjoy the feel of iOS but for her it is perfect.
