An alternative to the Nexus 5X 16GB. For the extra $41 for the Moto G4 Plus 16GB you'll get a newer model phone, Motorola instead of LG, Dual Sim (4G/3G), SD Card slot, slightly better battery life (reported) & a higher megapixel camera. However the Nexus 5X has NFC, is $41 cheaper and previous comments suggest a better processor. Thanks erland & Ausdroid review. If you need NFC go Nexus 5x, if you need SD card Moto G4 Plus.
The 32GB/3GB RAM model is also available for $378.93, not the best price yet but still decent and good value. For the extra $68 you'll get an extra GB of RAM and extra 16GB of storage.
Note that this is not the regular Moto G4, this is the Moto G4 Plus which includes a fingerprint scanner, better camera & an extra GB of RAM on the 32GB model.
According to DXOMARK, this phone's camera is on par with the likes of Nexus 6p & iPhone 6S Plus https://www.dxomark.com/mobiles.
