Xperia Z3 has a score of 77.3, which is just a bit better than the Xiaomi Mi 6's 76.5 global score. Despite being the best in this comparison review, it must be noted that it's also notably older, a little heavier and thicker. Xperia Z3 and Xiaomi Mi 6 both feature really similar processors, because although the Xperia Z3 has a lower number of cores and a smaller amount of RAM, it also counts with an extra GPU.
The Sony Xperia Z3 features a better looking screen than Xiaomi Mi 6, although it has less bright screen, they both have the same pixel density, exactly the same 1920 x 1080 pixels resolution and a screen with the same size. The Xiaomi Mi 6 has a lot bigger storage to install applications and games or saving photos and videos than Xperia Z3, because although it has no SD memory card expansion slot, it also counts with more internal memory capacity.
Xiaomi Mi 6 counts with just a bit longer battery duration than Sony Xperia Z3, because it has a 3350mAh battery size. The Xperia Z3 counts with a slightly better camera than Xiaomi Mi 6, because although it has a smaller diafragm aperture which is not nice for capturing photos or videos in low-light situations, and they both have the same video frame rate and the same (4K) video definition, the Xperia Z3 also counts with a way larger sensor which provides a lot higher image and video quality and a way higher 20.7 mega-pixels resolution back-facing camera.
In addition to being the best phone between the ones we are comparing here, Sony Xperia Z3 is also by far the cheapest one, which makes it a no doubt choice.
