Samsung - Galaxy Watch 6 Classic vs Garmin - vívoactive 5

The vívoactive 5 edges ahead on the Mars Score (48.9 vs 53.3), but the 4.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Galaxy Watch 6 Classic 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 peak brightness, display size, ecg, among others.

Pick the vívoactive 5 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, weight.

Both ship with comparable spo2, water resistance, 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.
