Which should you buy?
The OnePlus Open 2 is the clear pick on raw spec strength, leading by 14.3 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, water resistance.
Pick the OnePlus Open 2 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, wireless charging, 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: the OnePlus Open 2 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
