Verdict: Nothing Phone (4a) Pro ahead on 2 rows, Nothing Phone (3a) on 1 row
On the makers’ published figures, the Phone (4a) Pro wins on peak brightness (5,000 nits against 3,000 nits) and battery per charge (63.4 h against 43.93 h); the Phone (3a) wins on storage (base) (256 GB against 128 GB). One gap is borderline, a difference most people would not notice: RAM (12 GB against 8 GB) for the Phone (3a). The differences in weight, display size and battery capacity are below the thresholds you would notice. Both state the same typical brightness, battery lifespan and fast charging. The other 31 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.
