The real decision
This is design compliance versus coaching depth.
Withings ScanWatch 2 wins when the watch has to look normal. It is for the buyer who wants sleep, ECG, SpO2, temperature, and heart-health signals without wearing something that looks like a sports tracker. Garmin Venu 3 wins when the data has to steer the day. Sleep Coach, Body Battery, HRV status, workouts, GPS, and the AMOLED screen make it a more active recovery platform.
Both can work without a required monthly subscription. The question is whether you want the tracker to disappear aesthetically or push you harder behaviorally.

Buy Withings ScanWatch 2 if
Buy Withings if normal-watch design is the reason you will wear it. The analog face, long battery life, ECG, SpO2, temperature tracking, sleep scoring, and respiratory insights make it a strong health watch for people who dislike fitness-watch aesthetics.
It is also the better pick if charging friction ruins sleep tracking for you. The battery advantage is real commercially because a tracker on the charger does not collect sleep data.

Buy Garmin Venu 3 if
Buy Garmin if you want more active coaching. Sleep Coach, Body Battery, HRV status, workouts, GPS, stress, Pulse Ox, and a large AMOLED display make it the better recovery watch and the better workout companion.
Garmin is also the stronger pick if you want one watch to handle sleep, training, health, and everyday smartwatch utility without a required monthly sleep subscription.
Read the full Garmin Venu 3 review if subscription-free recovery coaching is your main buying reason.
Price discipline
Withings is not the budget pick just because it has less smartwatch depth. Buy it because the design makes you wear it more. Garmin is not automatically the better buy because it does more. Buy it because you will actually use the coaching, workouts, GPS, and recovery data.
The clean rule: choose Withings for passive health tracking in a normal watch. Choose Garmin for active recovery coaching in a real smartwatch.
