Which should you buy?
The ROG Phone 9 Pro is the clear pick on raw spec strength, leading by 17.5 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the Razr 50 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 weight, pixel density, screen size, among others.
Pick the ROG Phone 9 Pro if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are antutu, ram, wired charging, among others.
Both ship with comparable main camera, 5g support, front camera, so those specs don't separate the two — focus on the differences below.
Bottom line: the ROG Phone 9 Pro is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
