Having owned both the moto Z Force and 6p, I can tell you there isn't really much difference between the two devices other than the obvious Moto mods and the over $700 price of the Z Force. Performance real world pretty much identical with both. Both stock android so both identical there too. I would think you would see a small performance difference between the 6p and Z Play though. Even real world. Just a matter of if you want the mods and a tad or just slightly slower device. I'm unsure of resolution on the Z Play but I think its only 1080p compared to the top of the line 6p resolution which was identical to my Z Force. My thoughts are that the 6p is a superior device compared to the moto play and is better compared to the moto Z or Force. I'm sure the play is great but it'll be more about if you want the mods are not if you go Z Play over the 6p. If you get a moto, go for the regular Z if you want a very similar device to the 6p but sadly you loose the bang for your buck too.
