Verdict: nothing you’d notice between them
On the makers’ published figures, neither the Garmin fēnix 9 43mm nor the Garmin Venu 4 41mm wins a row by a gap you would notice. 2 gaps are borderline, differences most people would not notice: case size (43 mm against 41 mm) and weight (case only) (33 g against 44 g) for the Garmin Venu 4 41mm. Both state the same battery life (maker's claim). The other 9 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.
