Score: 82/100Rankings

The Fitbit Sense 2 is a premium health-focused smartwatch offering comprehensive sensors like ECG, skin temperature, and SpO₂ alongside built-in GPS and up to six days of battery life. Its heavier weight and lack of Wi-Fi connectivity limit its appeal for users seeking a lighter, more standalone device. Ideal for health-conscious athletes who value deep analytics.

Garmin Forerunner 165 is an entry-level GPS running smartwatch featuring a vibrant AMOLED screen, up to 11 days of battery life, and comprehensive health metrics like Pulse Ox and recovery insights. It lacks advanced multi-sport modes and built-in music storage, which may limit power users. Best suited for beginners to intermediate runners who value a bright display and long endurance.
