What apps are so bad? I have access to multiple iOS and Android devices where apps for both OS seem to work very similarly.

More later, but I have a friend with an iPhone who constantly beats me in a modified version of "Name that Tune", where she routinely beats me in accomplishing a task more quickly.

When we switch devices (I current have an HTC One) and I have the iPhone, I always win. And I don't want to give the iPhone back.
