Which should you buy?
The OnePlus 13R is the clear pick on raw spec strength, leading by 8.1 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 iPhone 15 Pro Max 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 pixel density, water resistance, promised os updates, among others.
Pick the OnePlus 13R 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 wired charging, ram, antutu, among others.
Both ship with comparable refresh rate, 5g support, optical image stabilization, so those specs don't separate the two — focus on the differences below.
Bottom line: the OnePlus 13R is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
