The vivosmart 5 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 Galaxy Fit 3 if you care most about sport modes / battery life. Its strongest claims are sport modes, battery life.
Both ship with comparable gps, spo2, water resistance, so those specs do not separate the two — focus on the differences below.
