Garmin Forerunner 965 vs Samsung Galaxy Watch 5 Pro
The Verdict
Garmin's Forerunner 965 excels for serious athletes with its exceptional 23-day smartwatch battery life and specialized training features, though it lacks ECG capability. Samsung's Galaxy Watch 5 Pro counters with a full suite of health sensors including ECG, superior Wear OS 3.5 software ecosystem, cellular connectivity, and impressive 80-hour power-saving mode,all at $150 less. Display quality is nearly identical (both AMOLED, 450+ resolution), but Galaxy Watch 5 Pro's lighter titanium build (46.5g vs 53g) and tighter water resistance (IP68/MIL-STD) suit everyday users better. Forerunner 965 wins decisively for ultramarathon runners prioritizing battery longevity and detailed training analytics. However, Galaxy Watch 5 Pro delivers superior overall value, richer smartwatch functionality, and broader compatibility with Android/iOS ecosystems. Choose Forerunner 965 if training data matters most; select Galaxy Watch 5 Pro for balanced health tracking, connectivity, and smart features.
