Which should you buy?
These two are nearly even on the Mars Score (71.7 vs 73.8). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the X200 if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.
Pick the Xiaomi 15 Ultra 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 wireless charging, ram, pixel density, 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.
