Verdict: nothing you’d notice between them

On the makers’ published figures, neither the Apple Watch SE 2 44mm nor the Apple Watch Series 8 41mm 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 and battery life (maker's claim). The other 25 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.
