Verdict: Nothing Phone (4a) ahead on 2 rows, Nothing Phone (3a) Pro on 1 row

On the makers’ published figures, the Phone (4a) wins on peak brightness (4,500 nits against 3,000 nits) and battery per charge (51.45 h against 43.28 h); the Phone (3a) Pro 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) Pro. The differences in weight, display size and battery capacity are below the thresholds you would notice. Both state the same refresh rate, typical brightness, battery lifespan and fast charging. The other 30 rows have no threshold or no direction to judge by, so nobody wins them.

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.
