I installed the Nexus Experience ROM in the Moto G of a friend of mine.
These are the files I used:
Android6.0.1_NX_R10.0.4_MotoG2014.zip NX-GAPPS_M_Release1.2_STD.zip TWRP_2.7.1.1.img
These files (except TMRP) can be downloaded from here.
This version is lighter than stock Motorola version because it is a pure Nexus base system.
