The real decision
This is not just Apple versus Fitbit. It is full smartwatch versus cheap sleep band.
Apple Watch Series 11 is the better product if you want the device to do more than sleep. It handles workouts, safety features, calls, apps, notifications, Apple Health, sleep score, and sleep apnea notifications. Fitbit Charge 6 is the better buy if you mainly want to test sleep tracking without spending smartwatch money.
The expensive mistake is buying Apple when you only need a sleep score. The cheap mistake is buying Fitbit when you actually want an iPhone watch.

Buy Apple Watch Series 11 if
Buy Apple if you already use iPhone and want the sleep tracker to be your daily wearable too. Sleep score is only one part of the value. The real value is Apple Health, workouts, safety features, apps, calls, messages, and notifications in one device.
Apple is also the better buy if sleep apnea notifications matter. Fitbit is a good sleep tracker for the price, but it is not the same health-and-safety platform.

Buy Fitbit Charge 6 if
Buy Fitbit if price and simplicity matter most. Charge 6 is the practical first sleep tracker: Sleep Score, sleep stages, heart-rate context, Google Wallet, Google Maps, built-in GPS, and up to 7 days of battery life.
Fitbit is also easier to justify if you are not sure sleep tracking will change anything. Buy the cheaper device, prove the habit, then upgrade later if you want a broader platform.

Price discipline
Apple Watch Series 11 is worth the premium only if you use the extra features. If you do not care about apps, calls, safety tools, workouts, and Apple Health, do not pay Apple Watch money for a sleep score.
Fitbit Charge 6 is worth buying when it stays meaningfully cheaper than a full smartwatch. If you start adding paid Premium because you want deeper recovery coaching, compare Garmin before turning Fitbit into a subscription decision.
