Fitbit Sense 2
Score: 82/100
Apple Watch Series 8
Score: 81/100Rankings
The Fitbit Sense 2 is a health-focused smartwatch offering ECG, stress monitoring, skin-temperature tracking and solid GPS capabilities with a 6-day battery life. Limitations include regional ECG availability, lack of Wi-Fi and modest music storage. Best for users who prioritize advanced health metrics over extensive media features.
The Apple Watch Series 8 GPS 45 mm offers a premium OLED display, fast S9 processor and a full suite of health sensors. Its drawbacks are the need for daily charging and the lack of cellular capability in the GPS-only version. Ideal for iPhone users who want top-tier health tracking without cellular independence.

Professional reviewers highlight the Sense's advanced health toolkit—cEDA stress monitoring, skin temperature tracking, and SpO2 measurement—as innovative steps beyond typical fitness trackers, while noting the limited regional availability of the ECG feature.
Professional reviewers commend the Series 9 for its ultra-bright 2000-nit display, the speed of the new S9 processor and the innovative Double Tap gesture, calling the interaction "magical." They also highlight richer workout visuals and Precision Finding via UWB, while noting that the GPS-only model still needs daily charging and lacks cellular capability, and that the weight gain over the 41 mm version is marginal.
Everyday users praise the watch's seamless iPhone integration, reliable fitness and health tracking, and the readability of the bright screen. Common complaints revolve around the need to charge daily, occasional sync hiccups with the iPhone, and band comfort issues for smaller wrists.
