Garmin Forerunner 945 vs Samsung Galaxy Watch vs Apple Watch Series 4: Which is Better?
Although all three smartwatches are fantastic choices and outstanding in design and features, I go with the Galaxy Watch. However, the now discontinued Apple Watch 4 is the best choice for iPhone users as it does not support Android platform.
On the other hand, for more serious fitness tracking with a longer battery life that allows you go long on a single charge, the Forerunner 945 is undoubtedly the best choice.
