Apple Watch SE 2 (2023) vs Fitbit Versa 4
Apple Watch SE 2 excels in ecosystem integration, performance, and display technology with its Retina LTPO OLED screen and Apple S8 chip, though it lacks advanced health sensors like ECG and SpO2. Fitbit Versa 4 compensates with comprehensive health tracking features—ECG, SpO2, and skin temperature monitoring—plus exceptional 6-day battery life versus SE 2's 18 hours, making it ideal for fitness-focused users prioritizing health data. SE 2's 44mm Retina display offers superior visual clarity, watchOS 10 provides deeper iPhone integration, and NFC enables Apple Pay everywhere. Versa 4's lighter price ($179 vs $249) and superior battery longevity appeal to practical buyers. Choose SE 2 if you're invested in Apple's ecosystem and want premium performance; select Versa 4 if health metrics and battery endurance matter more than premium features.
