I've gone from Iphone 4s and S2 to Xperia Z.
The phone is damn right awesome and it is probably the best phone I have owned to date.
In terms of processing, the One, Z and S4 are about the same with.
In terms of design, one could argue it is subjective, however, the Z IMO just looks amazing.
In the end, I chose to go for the Z due for a very simple reason - build quality.
I have had Iphone's smash on me and I have had the S2 do the same. Yes, I know you can buy covers etc, but at times, they don't help.
The fact the Z is water proof and 4 times stronger that gorilla glass used by rival handsets, it made it a no brainer for me and it does all this and still remains to be beautiful.
Also, if you buy the Z or any NFC Android phone, I recommend buying the Sony Smart watch and the Sony SRS BTM8 speaker.
The Sony Smart watch is only about £65 online and it connects to the phone. Unlike the pebble which is black and white retails at around £400 for Iphone, this is not only cheaper but offers far more apps.
The Sony SRS BTM* speaker is not only portable, but it has NFC, wireless and bluetooth. You can play music using any of the above, but more importantly, it has a built in speaker which also allows you to answer calls.
