Verdict: Garmin Venu 4 41mm ahead on 1 row, Galaxy Watch9 40mm on none
On the makers’ published figures, the Garmin Venu 4 41mm wins on battery life (maker's claim) (240 h against 40 h). One gap is borderline, a difference most people would not notice: case size (40 mm against 41 mm). The difference in weight (case only) is below the threshold you would notice. The other 26 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.
