Amazfit - Band 7 vs Coros - PACE 3 (as fitness tracker)

These two are nearly even on the Mars Score (73.1 vs 71.2). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the PACE 3 (as fitness tracker) if you care most about gps. Its strongest claims are gps.

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.
