Huawei - Watch GT 6 vs Withings - ScanWatch 2

The ScanWatch 2 is the clear pick on raw spec strength, leading by 8.8 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the Watch GT 6 if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are display size, weight, peak brightness.

Pick the ScanWatch 2 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are battery life.

Both ship with comparable ecg, cellular, spo2, so those specs don't separate the two — focus on the differences below.

Bottom line: the ScanWatch 2 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
