I've used both platform, and I find iOS user friendly and easy to use. I also found iOS easier to develop for than Android, though admittedly it's been a few years since I've developed on either. Opinions are funny like that.
Just to give an example, it is quite easy to build Android apps in a CI, while iOS is a pain (specially because there is no way to build an iOS app in anything other than a Mac). Also, most bugs specific to a platform happens in iOS (they happen in Android too, but my experience is maybe 10 bugs in iOS for 1 in Android).
