Rotating bezel: The LG Watch Sport has a rotating crown with the updated Android Wear 2.0 user interface that takes advantage of such a rotating mechanism. Crowns are small and have limited circumference, but the rotating bezel on the Gear S3 is innovative and highly functional.
Design and style: The Samsung Gear S3 Frontier is constructed of stainless steel, glass, and plastic with classic watch looks. The LG Watch Sport is also made of these materials, but it is even chunkier than the Gear S3 and looks more simple than the Gear S3.
Replaceable bands: LG built the LTE antennas into the bands of the LG Watch Sport so the elastomer bands you purchase are your only options. Samsung embeds everything into the watch body itself and gives you the ability to quickly and easily swap out the bands for standard ones readily available online. The Strap Studio bands are reasonably priced and look fantastic.
Samsung Pay: Android Pay is now available on the LG Watch Sport, but the more universal Samsung Pay with MST support is present on the Gear S3 Frontier. It is handy to pay for things while out and about without your smartphone and Samsung Pay continues to add financial institutions and programs.
Activity tracking: The LG Watch Sport supports GoogleFit and third party apps while the Gear S3 relies on S Health. We've seen a ton of improvements in S Health and the automatic activity tracking is tough to beat on the Gear S3. Plenty of third party apps and services are also supported on the Gear S3.
The LG Watch Sport may have better apps, but all of the data studying smartwatch usage has shown that the key to success with smartwatches is in performing the core functions better than others. These functions include informing the user of the time, tracking activity, triaging communications, and interacting with the voice assistant.
The Apple Watch accounts for half of all smartwatch sales, but the smartwatch market still hasn't garnered massive demand. I like to wear a watch, and over the last couple of years all I have worn is smartwatches. Once you start wearing one daily and use it to triage email, track your activity, make calls while your phone is tucked away, and use it to quickly check some basic info, it becomes a device you don't want to leave behind.

With Apple, LG, Huawei, Asus, and Samsung still making new smartwatches, I think this market will eventually get the attention of the masses, but it is going to take longer than the adoption rate we have seen with smartphones.
