Moto 360 vs LG G-Watch R vs Samsung Gear S - size, specs & features comparison

With the announcement of the Moto 360, the smart-watch "circle" is now complete. We have three different devices from established vendors, and each presents its own viewpoint of how a smart-watch should look and feel, and what it should be able to do. While the Moto 360 and LG G-Watch R want you to feel like you're wearing a regular watch, the Samsung Gear S is more like a miniature smartphone strapped on your wrist. 

The trade-off in design and weight appeal is that the Gear S is the only stand-alone smart-watch by far. It's the only one you can bring outside without a smartphone in your pocket, and don't miss out on any vital functionality - be it calls, messages, or even apps. Not that the other two aren't capable tickers on their own, with their Android Wear functionality offering plenty of untapped potential. Each smart-watch has its own unique charm, and here's how they stand up to each other. Which one do you like best?
