Nothing - Phone (3a) vs OnePlus - Nord 4

The Nord 4 edges ahead on the Mars Score (62.5 vs 65.8), but the 3.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the Phone (3a) if you photograph or shoot video regularly and want the better imaging pipeline of the two. The biggest gaps in its favor are front camera, screen size.

Pick the Nord 4 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are wired charging, ram, antutu, among others.

Both ship with comparable main camera, refresh rate, 5g support, 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.
