Verdict: nothing you’d notice between them

On the makers’ published figures, neither the Google Pixel Watch 4 41mm nor the Galaxy Watch8 44mm wins a row by a gap you would notice. The difference in weight (case only) is below the threshold you would notice. Both state the same peak brightness. The other 30 rows have no threshold or no direction to judge by, so nobody wins them.

True to scale

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.
