Which should you buy?
The ROG Phone 9 edges ahead on the Mars Score (71.3 vs 75.1), but the 3.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the OnePlus 13R 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 wired charging, weight, pixel density, among others.
Pick the ROG Phone 9 if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are front camera, refresh rate, ram, among others.
Both ship with comparable main camera, screen size, 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.
