Which should you buy?
These two are nearly even on the Mars Score (63.4 vs 65.3). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
The Galaxy Fit 3 does not pull ahead on any single popular-comparison spec — its strengths sit in the spec-table groups rather than the headline advantages.
Pick the 5.0 if you care most about sport modes / battery life. Its strongest claims are sport modes, battery life, water resistance.
Both ship with comparable gps, spo2, so those specs do not 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 says both are well-rounded; the differences are about trade-offs, not quality.
