I had an xperia z, at the time when I purchased the device it was up there as one of my favorite smart phone devices, BUT it was slower cearly than the iphone 5 was.. and my current device the nexus 5.. reason being the device was running on snap dragon 400.. (clocked a littler higher than the galaxy s III), water resistance was great.. camera was great..
BUT THE Z1 is a HUGE improvement.. super snappy, better camera, slightly better screen.. but overall when I had the xperia z I would say it was sony's best smartphone at the time.. clearly they have improved drasticly on the device.. with the z2 being one of the top 3 best smartphone devices money can buy today (according to critics and android stans)
