I had the Gear 2 and then went with the 360. At first, I missed the Gear 2 because it felt like it had more interactivity and it seemed more mature. I wound up returning the Moto 360 and then kept the Gear 2. A month later, I purchased the Moto 360 once again and kept the 360 until I upgraded to the Gear S. When I took the 360 off my wrist to put the Gear S on, I was sad. To this date, I am still torn between the Gear S and the 360. I like the big display of the Gear S but, hate the app store. I also do not like to be chained to a Samsung device either. With the Moto 360, I really like the Google Now integration into the device. I also liked the wireless charging that the 360 had along with when you put it on the cradle, it would turn into a nice night time clock.
So in summary, I would vote for the Moto 360. I really like the looks of the Asus Zen watch as well. But, that has a square display. Another thing, I liked about the 360, was the variety of bands and watch faces. Changing the band on the 360 is much easier than the Gear watch.
