The Moto X Pure was a big letdown for me. The original Moto X had a OLED screen, whereas the pure was backlit. I didn't realize that until after I bought it. I should have done more research, but I didn't think they'd make it worse. The camera was a little better. But, nowhere near as good as the Nexus 6.
I love waving my hand over it to check notifications too.
I'm looking to upgrade soon too, and I think I'll probably end up with a Pixel, or Pixel2.
