Xiaomi Smart Band 9 Midnight
Score: 80/100Rankings

The Fitbit Charge 6 is a slim, lightweight tracker with a bright AMOLED display, built-in GPS and a full suite of health sensors. Its main trade-offs are the mandatory Google account, proprietary charger and lack of an official IP rating. Best suited for beginners to intermediate fitness enthusiasts who value Google services and comprehensive health tracking.

The Xiaomi Smart Band 9 offers a bright 1.62-inch AMOLED screen, ultra-light design and long battery life for everyday fitness tracking. It sacrifices built-in GPS and a higher-resolution display, which may disappoint power users. Best suited for budget-conscious users who prioritize comfort and basic health metrics.
