Which should you buy?
The Venu 4 edges ahead on the Mars Score (58.5 vs 53.5), but the 5.0-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Venu 4 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are battery life, weight, display size.
The Vantage V3 similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
Both ship with comparable ecg, cellular, spo2, so those specs don't separate the two — focus on the differences below.
Bottom line: the Venu 4 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
