I don't have the Z Force, since I am not on VZW, but I have the unlocked Moto Z on AT&T and I also have the Pixel XL. I will likely return the Pixel, but I have not decided yet. I really like the Z. The Pixel does not have the fingerprint reader on the front, ambient display and the Z is just as fast, if not faster. If you want Google Assistant, the Pixel is better -- I do not use it and have heard that it is not very good, yet. The Pixel is also on Nougat, but the Z line is rumored to be getting it. The Pixels will be updated much more frequently than the Z line, without a doubt. I still prefer the Z. Both have good cameras. I like the form factor of the Z better. The Pixel XL is blocky and not very attractive, in my opinion. If you go to the Pixel forum and say anything other than singing the praises of the Pixel you will be lambasted, but I have had every phone out there for the last few years and I think the Z line is very near the top of the list.
