Verdict: Garmin Venu 4 45mm ahead on 1 row, Galaxy Watch8 40mm on none
On the makers’ published figures, the Garmin Venu 4 45mm wins on battery life (maker's claim) (288 h against 40 h). One gap is borderline, a difference most people would not notice: weight (case only) (30 g against 38 g) for the Galaxy Watch8 40mm. The other 27 rows have no threshold or no direction to judge by, so nobody wins them.
Specifications
A win is marked only where the figures can be ranked and the gap is one you could notice on the wrist. A row the site has no threshold for says whether the two differ, and that it is not ranking them. = marks the same figure on both, ≠ not ranked a difference with no ranking. Every figure carries its source.
