Which should you buy?
The V40 Pro edges ahead on the Mars Score (63.2 vs 67.6), but the 4.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Pixel 9a if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, promised os updates, wireless charging.
Pick the V40 Pro if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are front camera, wired charging, ram, among others.
Both ship with comparable refresh rate, 5g support, water resistance, 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.
