Which should you buy?
The X Fold 3 Pro is the clear pick on raw spec strength, leading by 10.6 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 Phone (3a) if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.
Pick the X Fold 3 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, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
Bottom line: the X Fold 3 Pro is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
