Which should you buy?
The OnePlus 13 edges ahead on the Mars Score (68.7 vs 73.8), but the 5.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Phone (3) if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, promised os updates.
Pick the OnePlus 13 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 wireless charging, wired charging, ram, 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 13 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
