Lumia 950 in my hand.
Quick first impressions:
Feels much lighter than my Lumia 930. Slightly larger in my hand but definitely thinner overall. Love the matte white finish. It's very elegant looking and gives a nice grip while holding it.
All of my settings and contacts synced perfectly (including my alarms).
AT&T HD Voice does work and is active. You'll see the text "AT&T HD Voice" when making a phone call to a compatible phone (my wife's 950 in this case). LTE remains active during the call.
Screen is not as good as the 930. Much dimmer overall. I'm not impressed with that as it's going to make using it outdoors a lot worse. Might have to pressure Microsoft to push a firmware update or something. The colors look accurate and vibrant, but dimmer is not better in the cell phone world. I turned off automatic brightness and set it to 100%. The photo below tells the story.
By the way, the photo below was taken on my wife's 950. The 930 is on the right.
