Which should you buy?
The X Fold 3 Pro edges ahead on the Mars Score (65.6 vs 73.1), but the 7.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Razr 50 Ultra 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, refresh rate, pixel density.
Pick the X Fold 3 Pro if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are wireless charging, wired charging, battery capacity, among others.
Both ship with comparable main camera, 5g support, water resistance, so those specs do not 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.
