Garmin - Lily 2 vs Garmin - vivosmart 5

The vivosmart 5 edges ahead on the Mars Score (46.1 vs 50.7), but the 4.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Lily 2 if you care most about sport modes. The biggest gaps in its favor are sport modes.

Pick the vivosmart 5 if you care most about battery life. Its strongest claims are battery life.

Both ship with comparable gps, 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.
