Google - Fitbit Inspire 3 vs Google - Fitbit Luxe

The Fitbit Inspire 3 edges ahead on the Mars Score (66.4 vs 63.2), but the 3.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Fitbit Inspire 3 if you care most about battery life / sport modes. The biggest gaps in its favor are battery life, sport modes. The single most decisive one: Battery life — 100.00% more. 10 days vs 5 days.

The Fitbit Luxe similarly does not 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 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.
