Fitbit excels in sleep tracking with detailed sleep stage analysis (REM, deep, light), sleep scores, and advanced insights. Apple Watch provides basic sleep and wake time detection but lacks the detailed sleep architecture analysis that Fitbit offers. If sleep optimization is a priority, Fitbit is the superior choice.
