Which should you buy?
These two are nearly even on the Mars Score (74.5 vs 73.1). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
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. The biggest gaps in its favor are antutu.
Pick the X Fold 3 Pro if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are wired charging, weight, water resistance, among others.
Both ship with comparable battery capacity, ram, main camera, 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.
