I have had the Gear and Gear S. I currently have the Moto 360 for a 2nd time. The Gear was nice...very basic with Tizen. I got the Gear S and a prepaid sim, added the keyboard and it was awesome! I could leave my phone at home and totally communicate via the watch. Returned it after the "trial" period because it was just too big for my arm. The Moto 360 I got on release day a long time ago and ended up returning it due to battery life. I bought it again a couple weeks ago when Best Buy was doing the $100 off, so I got the stainless steel band version for $119...HAD TO BUY!
