dafman: The only negative I can think of is the 9mm thickness. Otherwise, looks great. Pity about Sense, but there always is the google now launcher. Definitely my pick over the S6, as has bigger battery and SD slot.
9mm isn't exactly BIG though...
Sense as an OEM UI "flavour" is pretty light compared to some others (I'm looking at YOU, Touchwiz!!) - as you say, you only need to run a different launcher (take your pick from the Play store) and it's as though Sense was never there. Can't say the same about the likes of Touchwiz, which futz with EVERYTHING POSSIBLE, so there will always be something remaining with them, even when running a different launcher...
