Amazfit GTS 4 vs Garmin Venu Sq 2
The Verdict
Both smartwatches deliver solid fitness tracking with AMOLED displays and multi-day battery life, but they cater to different priorities. Amazfit GTS 4 excels with a larger, sharper 390x450 AMOLED screen in a lighter 27g package, plus dual-band GPS for precise positioning and 8-day battery typical usage. Garmin Venu Sq 2 counters with superior endurance,11 days smartwatch mode, 26 hours GPS,plus NFC for contactless payments and Garmin's renowned sports software ecosystem. Health tracking is equivalent between both (SpO2, heart rate, sleep), lacking advanced features like ECG.

At $50 less, the Amazfit offers better value for casual fitness enthusiasts, while the Garmin justifies its premium for serious athletes demanding extended GPS tracking and Garmin Connect integration. Choose GTS 4 for everyday elegance; Venu Sq 2 for multi-sport endurance.
