The real decision
This is not just cheap tracker versus expensive tracker. It is a disposable experiment versus a watch you may wear for years.
Fitbit Charge 6 is the low-risk way to learn whether sleep tracking changes your habits. It gives you Sleep Score, sleep stages, heart-rate data, stress tools, GPS, Google Wallet, Google Maps, and a readable app at a much lower price. Withings ScanWatch 2 is the compliance play: it looks like a real watch, lasts for weeks, and collects sleep and health signals without looking like a fitness band.
The expensive mistake is buying Withings when you only need a cheap sleep experiment. The retention mistake is buying Fitbit when you know you will not wear a rubber tracker in normal life.

Buy Fitbit Charge 6 if
Buy Fitbit if you want a cheap, simple answer. Charge 6 is the better starting point for buyers who want Sleep Score, sleep stages, a readable app, heart rate, stress tools, Google Wallet, Google Maps, GPS, and a small tracker that does not cost smartwatch money.
It is also the better gift or parent-friendly buy. If the person may stop wearing a tracker after two weeks, Fitbit limits the financial damage.

Buy Withings ScanWatch 2 if
Buy Withings if design compliance is the point. ScanWatch 2 is for people who want health data but dislike the look of a fitness band. The analog face, long battery life, ECG, SpO2, temperature tracking, respiratory insights, and sleep trends make it a better long-term wearable if you will actually keep it on.
It is also cleaner if recurring fees irritate you. Withings+ can add more app guidance, but the hardware does not need a required monthly plan to make sense.

Subscription and ownership math
Fitbit is cheaper up front, but the best Fitbit coaching sits behind Google Health Premium. That does not make Charge 6 a bad buy. It means you should treat Premium as a separate software decision after you know you will wear the tracker.
Withings costs more up front, but the cleaner ownership model is the point. If you will wear the watch for years because it looks normal and rarely needs charging, the higher price can make more sense than buying a cheaper tracker you abandon.
Price discipline
Buy Fitbit Charge 6 near list price or on sale. It is strongest when it stays well below Garmin, Apple, Oura, and Withings money.
Buy Withings ScanWatch 2 only if the design and battery life solve a real wearability problem. If you do not care how the tracker looks, Fitbit is the better value.
