The G4 is ok but LG notoriously has a steep obsolescence curve while the Moto's last a little longer. One thing that sets the Moto apart from most other brands are the radios. If you live in an area of travel in areas with marginal coverage the Motorola is superior in that regard. At the end of the day it boils down to features and what you really need, what ever brand you pick make sure it does not have some weird problem with your car Bluetooth and other peripherals you already have. There is nothing worse than having a device that does not play well with your car or home automation. It may sound weird but despite having the same os version some firmwares do not work well with other devices or apps.
