Verdict: Motorola moto g57 power ahead on 2 rows, Nothing Phone (3a) on 2 rows
On the makers’ published figures, the moto g57 power wins on battery capacity (7,000 mAh against 5,000 mAh) and battery per charge (63.93 h against 43.93 h); the Phone (3a) wins on peak brightness (3,000 nits against 1,050 nits) and battery lifespan (1,400 cycles against 1,000 cycles). 2 gaps are borderline, differences most people would not notice: RAM (12 GB against 8 GB) for the Phone (3a) and fast charging (50 W against 30 W) for the Phone (3a). The differences in weight and display size are below the thresholds you would notice. Both state the same refresh rate and storage (base). 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.
