Now you see I have asked myself that question and its left me feeling a bit "meh". I bought it in the white a few months ago and generally loving the slim profile. The curved edge is crap, software doesn't really take advantage over it, its purely a gimmick. I think the standard S6 looks nice, I am quite boring in that way, S6 looks like a very polished device, where as S6 Edge is the same but charges on average £100 more.
To the OP the Edge in tandem with its like flexy sexy brother has the best screen on the market. They also use less energy as they run on a small die process compared to the Snapdragon 810 or Kirin 935 (admittedly the latter is more subjective); Ergo it uses less energy as @AlanWarric alluded to. Lack of expandable storage may be an issue, although it does come start at 32GB and upwards.
The problem with the Z5 is that some of the features are sadly lacking. 1080p screen, considering the rest of the market (Android wise) has moved to at least 2k in there flagships. Yes the Z5 premium is 4K, in realityit will likely be too expensive for most people to buy. When you compare the Z5 in its own right, it fails in comparison to the likes of LG G4, Samsung S6, Mi Note Pro, HTC One M9+ I could go on.
If you want a phone that is swift with updates go with LG, they are way and above the fastest to release new software which has a skin run on top. Those that use stock android like are usually quicker.
Mind saying this, two new nexus devices are due to be launched on 29th, large and small will be catered for.
