But, the Gear Sport being a new smartwatch does have one major standout point when compared to the Gear S3. This is because, the Gear Sport was more of a new category of smartwatches rather than a direct successor to the Gear S3 as that void will soon be filled with the announcement of the Gear S4. But shift that comparison to a generation ahead with the Gear S3 and the recently launched Gear Sport smartwatches, the differences in proving that the Gear Sport is the better device is mostly on the software level than in terms of hardware (with a couple of exceptions ofcourse). When we compare the the Gear S3 and the Gear S2, the differences between the two are quite substantial in both hardware and to some level software to prove that the Gear S3 is the better device.
