I had the G Watch for a week and returned it for the 360. There wasn't anything wrong with the G Watch, I just felt the 360 was more aesthetically pleasing. And it was, however I've come to discover that the Moto 360 really is the embodiment of the old saying "beauty is only skin deep". Ridiculously bad battery life, lags in apps and even UI scrolling, there are also less apps that natively support round faces (won't be a problem in a few months but right now Wear apps in general are already very limited). You couple that with a defective unit (mine has 2 stuck pixels) and a 70 dollar more price tag...Well, there's the Moto 360. In terms of advantages it has over the G Watch - there's the look, you can't argue that, and an extra heart rate monitor, that's it.
