Verdict: Galaxy S24 Ultra ahead on 3 rows, Galaxy S24 on 1 row
On the makers’ published figures, the Galaxy S24 wins on weight (167 g against 232 g); the Galaxy S24 Ultra wins on display size (6.8 in against 6.2 in), storage (base) (256 GB against 128 GB) and battery capacity (5,000 mAh against 4,000 mAh). 2 gaps are borderline, differences most people would not notice: RAM (12 GB against 8 GB) for the Galaxy S24 Ultra and fast charging (45 W against 25 W) for the Galaxy S24 Ultra. The differences in claimed video playback and Geekbench 6 (CPU, multi-core) are below the thresholds you would notice. Both state the same refresh rate, peak brightness and wireless charging. The other 33 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. 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.
