Which should you buy?
The ROG Phone 9 edges ahead on the Mars Score (75.1 vs 71.7), but the 3.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the ROG Phone 9 if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are refresh rate, ram, screen size, among others.
Pick the X200 if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are wireless charging, wired charging, weight, among others.
Both ship with comparable battery capacity, main camera, 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.
