So I give Sony another try knowing the issues with my S. But I'm very satisfied with my Z1. It is also fast, smooth and so on. Camera is good for me (hey, it's a Smartphone, no digicam) and about Sony Bloatware - root it and delete all this apps. Cloud-space I also have more then 600GB on my own server, but you can't move apps on the cloud and use it, so SD-Card is here a very important thing. Of course, Sony does not implentet apps2sdard like samsung, but with root it works and 64GB should be enough.
There is also the design and the haptic important. Plastic vs. glass and aluminium. For me waterproofness was not a decision criterion.
Sure, comparing phones is always with a touch of personal oppinion, but everyone knows why he own a N5 or Z1 or S4 or an half-eaten apple
