Is the Moto Z Play a big change from Moto X Play?

I have a Moto X Play, which is very nice. My wife's phone is getting some issues, so I'm thinking on maybe upgrading to the Z Play and leaving the X Play to my wife.

The main differences I see (from paper) are:
1. Build materials (metal/glass vs plastic).
2. Better processor.
3. I don't know about the camera, maybe a little better because of the auto focus tech).
4. More RAM and Storage.
5. Amoled vs IPS.

She's not too much into tech, so she just wants a reliable phone.
