The Fitbit Versa 4 is a modest upgrade on its predecessor but matches closely with the GTR/S 4. Amazfit has always excelled as a fitness smartwatch experience, and the company has doubled down with the GTS4/GTS4. Outdoor workouts have also been treated to extra biometric analysis via PeakBeats, tracking of track running, and also new mapping and routing. The Amazfit pair offers an overhauled heart rate sensor array on board, multiband GPS, 150+ workout modes, and intelligent detection of workouts, including gym repetitions. The GTS 4 has a more feminine design, but pretty much everything that applies to the GTR 4 can be found on the GTS.

We prefer the GTR 4, which is a masculine looking 46mm smartwatch. They're not identical, and the square version offers a tad more battery life. The Amazfit GTR/GTS 4 comes in round and square options.
