I just got one last week, love it so far. The 6.0 update works well, I'm ending my days of moderate use with about 25% battery left. Its a good size, and gets comments from people when I take it out of my pocket with the dot view case. Because of its lack of hit factor, they are ridiculously cheap online, got mine brand new on ebay with warranty for $260 bucks. Such a great value.
If you don't need SD card support, I reckon the S6 is just as good if not better if you can get it for close to the same price, but I needed that functionality. Otherwise, the camera is not nearly as bad as some have reported, maybe its the updates, maybe its the tweaking of the image settings I did, I also use the raw camera quite a bit,. Selfies are awesome as well. The screen is fine, but I don't like the auto-brightness, it over compensates and I find it dim and washed out in many situations. I leave it on the middle brightness.
Its also on track to get android 7.0, so its not out of date yet (although I imagine that's it for it, no 8.0)
