I like moving through apps better.
The UI and how I interact with it is better. I use Siri and find it works and it pleasant vs google was a bitch.
Camera is frustrating because I am not used to it yet but much more enjoyable to just shoot than anything I've used in a long time. I bet I would like the pixel more for the stills if I wanted to nitpick but this seems to shoot faster and the video is a lot better.
