Garmin Forerunner 965 vs Samsung Galaxy Watch 4 Classic
The Verdict
Garmin Forerunner 965 and Samsung Galaxy Watch 4 Classic serve different audiences with distinct strengths. Garmin's offering excels in battery longevity, delivering up to 23 days in smartwatch mode versus Samsung's typical 22-hour real-world performance. The 1.4-inch AMOLED display on Garmin (454 x 454 pixels) edges out Samsung's 46mm variant (450 x 450 pixels) slightly, though both are vibrant. Samsung counters with true ECG capability and optional LTE connectivity, plus superior build quality with stainless steel and Gorilla Glass DX versus Garmin's fiber-reinforced polymer. Health tracking favors Garmin with skin temperature monitoring absent on Samsung, while Samsung includes ECG which Garmin lacks. Wear OS 3.0 offers broader app ecosystem access compared to Garmin's more limited software library, though Garmin's fitness-focused interface wins for dedicated athletes. At $599 versus $349, Samsung undercuts Garmin significantly. Choose Garmin for ultramarathoners and outdoor enthusiasts prioritizing battery life and rugged construction. Pick Samsung if you want LTE, ECG data, better everyday smartwatch features, and don't mind charging every 1-2 days. Samsung delivers stronger overall value; Garmin justifies premium pricing through endurance sports expertise.
