Garmin - Venu 4 vs Garmin - Venu 3

The Venu 3 edges ahead on the Mars Score (58.5 vs 62), but the 3.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Venu 4 if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.

Pick the Venu 3 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, display size, cellular, so those specs don't separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
