As a GNex user, I was impressed with the S3. Very quick UI, bloatware wasn't all bad, and the size is great. I use an extended life battery in all of my phones so my GNex is fattened up a little bit. I will say this; I still wouldn't trade my GNex for the S3. After rooting the GNex, the UI flies through screens. So considering I had the chance to play with my coworkers S3, I thought I'd write my own review. Great phone, but the GNex still, in my opinion, wears the crown.
