Finally got mine all set up. Comparing the screen side by side with my Z2, I actually think the screen looks a little better. It's a bit more vibrant and has better contrast between black and white. I haven't found the need to mess with the white balance at all. Size feels pretty good but a tad on the small side. The next few days will tell if I can get used to it or not. I wish the body was just a hair bigger, somewhere between the Z2 and Z3c. Everything seems to be working fine, however I noticed my LTE speeds are low but I haven't compared that to people around me with AT&T so I'm not sure if that's a location issue or the phone. Speakers seem good. Notifications are a bit louder than they were on my Z2. I definitely miss the notification light bar on the Z2, but the little LED dot on the Z3c will do. Won't be able to really tell how battery life is for a few days, but it seems to be on par with the Z2. I've been on it non stop so I'll have a better idea with mixed use.
