I compared these camera twins in a variety of locations around San Francisco. Both phones were left in Auto HDR and iPhone pictures were saved as HEIC files instead of JPEG - A new file format that makes photo files smaller than JPEGs with minimal loss to image quality.

To my surprise, neither phone blew the other away. My comparison is all about the nuances in their photos and videos. You might prefer one over the other depending on your tastes.
