Which should you buy?
The Xiaomi 15 edges ahead on the Mars Score (63.2 vs 70), but the 6.8-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.
Pick the Xiaomi 15 if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are wireless charging, wired charging, front camera, 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: the Xiaomi 15 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
