Sony's Xperia Z2 was close to being the first Android with no compromises. Its large display and fantastic camera combined with speed performance, durability and insane battery life to amazing effect. It's been Cam's favorite device virtually all year, and so he wanted to compare it to its successor to see what has improved and what's perhaps not as good. 

Both phones feature a 5.2-inch 1080x1920 display, 20.7-megapixel rear camera, 3GB of RAM, Snapdragon 801 series quad-core chip and large batteries. But there are differences in design that give the Z3 a more sophisticated and elegant look. Despite only having lost 1mm in thickness, it feels smaller thanks to the more rounded edges.

What do you make of the Z3? Is it as good as the Z2, or are the compromises in the wrong places this time out?
