Had (have) the RARZi and bought Moto G just for curiosity, I never switched RZi on again besides for some camera comparisons, in which MG won massively in low light.
Performance wise it is black and white: The Intel Atom is very snappy, databases (SMS) open up slightly faster on RZi than on MG, but the overall performance goes to MG. Battery runtime is about the same, 2-3 days is easy.
Personally I like the AMOLED of RZi, but I got used to LCD in 2 days and now I really enjoy that fabulous display on MG. Brighter, sharper, sunlight readable. WIFI and GPS works hands down better on MG.
In palm of the hand the RZi is edgy and sharp, MG soft and smooth, I like that. Never missed the SD card (I hated it on RZi, because I always searched my files on the wrong place, internal, external, blah), same for NFC - I don't use it. Sound quality is Motorola like very good on both phones.
If I must buy a new phone right now: Moto G, no doubt.
That is my subjective opinion but I hope this helps.
