Both have their pros and the cons. Moto 360 basically looks way better. It also has a heart rate monitor which I like but it isn't a must. On the other hand Smartwatch 3 has a much smoother interface, better battery, is cheaper and has micro USB for charging.
My main problem is this - I am a pretty small guy and I have small wrists as well. So a big watch would just look ridiculous on me. My wrists are about 46mm in diameter at the widest point where the watch would sit. So that's a big issue and the determining factor will be the size. I know that the Smartwatch 3 is slightly larger in one dimension, but it is designed much differently and is thiner. But it is pretty new and I haven't seen much comments about its size.
Anyone with similar issues? What would you suggest?
