[Galaxy S6 Edge Accessories] flarbear:
I started out with Pebble from the initial launch, but could never get over the fact that the low resolution display had jagged edges that could be seen from space (well, OK, I exaggerate a tad), and the feeling like the case was designed and manufactured by Fisher Price. Even the colors, which looked great on the web site and kickstarter videos arrived looking a bit more like lego plastics. Still, it did a pretty good job of presenting the notifications. I used the Pebble for a few months before the Samsung watches came out (and then I didn't get the original Gear until it had been out for a couple of months). The Pebble Steel does improve the looks of the watch by a wide margin, but the display did not look any/much better.

I then tried Galaxy Gear (original), Gear Live, and Gear 2 (full size one with camera). The Gear Live went back within a week as Android Wear offered so little functionality compared to the original Gear. I thought the Gear 2 looked a lot better than the original Gear despite being so similar in design, but the few changes made a nice difference and it felt better on my wrist. I used the Gear and Gear 2 each for several months.

When the ZenWatch came out, though, I was really impressed by how it looked on the wrist. The Moto 360 never really spoke to me from a style perspective and the complications of a round display just seemed to me that they would eventually limit what I could accomplish with it compared to the rest of the mobile/personal world that was centered around developers thinking about square presentation spaces. I love the ZenWatch looks and how it fits my wrist (and the bands are a fairly standard size and attachment compared to the Gear watches so you get a limitless selection for bands). I do miss a bit of the customization of the Gear capabilities at times, but Android Wear does win on the day to day stuff of notifications, ease of dealing with notifications, ease of dictating/sending text messages, and integration with navigation. I'll take those over the added functionality of the Gear in the long run, but I do wish Android Wear had a better focus on apps rather than just "notifications on steroids" (when I try to run a non-notification app I get frustrated with the process compared to just swiping across a number of app screens on the Gear devices). If Android Wear would even just offer a way to look back at old notifications it would make a huge difference - the Gear watches would both notify you of current notifications and they also had a screen to go to to see past notifications and even read full emails if you wanted. The Android Wear "cards" do let you click through to read more of the message when you get the notification, but once you dismiss the notice you can never get back to it on the watch.

I don't think Gear had navigation integration when I was using those watches (they may have gotten it since then), but the Android Wear does do an excellent job of keeping upcoming navigation steps at a glance on my wrist.

It will be interesting to see how the Apple Watch motivates Samsung and Google to improve either system.

In the meantime, I've been meaning to try the Gear 2 out again and see what enhancements they've added and how well it works with my S6 Edge...
