Nothing - Phone (3a) vs Nothing - Phone (3a) Pro

These two are nearly even on the Mars Score (62.5 vs 63.8). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Phone (3a) if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.

Pick the Phone (3a) Pro if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are front camera, ram, antutu.

Both ship with comparable battery capacity, main camera, screen size, so those specs don't separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
