Between the Phone (3a) Pro and V40 Pro, the Phone (3a) Pro comes out ahead in several specs, while the V40 Pro wins on antutu and wired charging. Overall, the Phone (3a) Pro scores 63.8 and the V40 Pro scores 67.6 on our Mars Score.
Which should you buy?
The V40 Pro edges ahead on the Mars Score (63.8 vs 67.6), but the 3.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The Phone (3a) Pro doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
Pick the V40 Pro 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 antutu, wired charging, weight, among others.
Both ship with comparable ram, main camera, refresh rate, 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.
