My iPhone 4S benefited immensely from iOS7 (UX-feel not withstanding). The biggest difference for was in the camera software. I can't describe how much better it is performing in filming things as they happen.

By contrast, my Galaxy Nexus has become slower and slower with each upgrade. With the last update, my keyboard started to crash... I was really looking forward to the 4.4, hoping things would improve.

And yes, I use two phones and most of the time have both with me... GN is no longer used as a camera though.
