Verdict: Garmin Venu 4 41mm ahead on 2 rows, Galaxy Watch Ultra2 47mm on none

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.
