Apple - Watch SE 3 vs Garmin - Venu 4

These two are nearly even on the Mars Score (56.1 vs 58.5). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Watch SE 3 if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are display size, weight, cellular.

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. Its strongest claims are battery life, ecg, spo2.

Both ship with comparable water resistance, peak brightness, 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.
