1st thing I tell u that it have faster processor than redmi note 3 it have better camera than redmi note 3 the we do the speedtest b/w the lenovo zuk z1 and moto g4 plus suprisingly the zuk z1 win the speed test without any lagging.
The difference b/w the moto g4 plus and the zuk z1 is the camera the moto g4 plus has slightly better camera than zuk z1 and other things are almost same where the moto g4 plus gives plastic body whereas the zuk z1 offer mettalic body the zuk z1 is best smartphone.
