SONY XPERIA XZ is new Sony's flagship lineup alongside much awaited Apple's IPHONE 7 and 7+.
Now,if we see the specs of xz and iphone 7,we technically find that former falls sort of any competition.Okay, let me say clearly
(no offence to iphone 7) but xz beats it almost all fields.

Above links might be useful if you go through.
I think that camera and processor are deciding factors.
And ofcourse, battery goes without saying.
Sony is better in this context (battery backup).
cameras on both the phones are good but i think sony may have an edge due to extra pixels.
Also, the new a10 chip in iphone is fast! (literally) and i can say the same for snapdragon chipset as it is made newly developed adreno 530 gpu. So its gotta be fast.
