I want to buy a SmartWatch and can't choose between these two. The price of the gt 2 is a little cheaper, the battery life is much better and the watch has more memory. The Galaxy watch active has more functions, the ability to download apps and also reply directly to messages. It is also a little more expensive. I can't really decide now or what do you think is the better SmartWatch?
If the functions such as message answering, apps download are necessary for you, you can buy Galaxy watch active.
Personally, I don't think it's necessary because I have a cell phone. And I can't compliment the small WATCH screen for interaction.
Just let it be a wrist watch.
