Which should you buy?
The Xiaomi 15 Pro edges ahead on the Mars Score (70.9 vs 74), but the 3.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Find X8 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 Pro if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are ram, pixel density, wired charging, 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.
