Which should you buy?
The MIX Fold 4 edges ahead on the Mars Score (63.5 vs 71.4), but the 7.9-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Xperia 5 V 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, pixel density, headphone jack.
Pick the MIX Fold 4 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 refresh rate, 5g support, optical image stabilization, so those specs don't separate the two — focus on the differences below.
Bottom line: the MIX Fold 4 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
