Which should you buy?
The Band 7 is the clear pick on raw spec strength, leading by 15.9 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the Band 7 if you care most about sport modes and battery life. The biggest gaps in its favor are sport modes, battery life.
The Inspire 3 similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
Both ship with comparable gps, spo2, water resistance, so those specs don't separate the two — focus on the differences below.
Bottom line: the Band 7 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
