Which should you buy?
The MIX Fold 4 edges ahead on the Mars Score (67 vs 71.4), but the 4.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Edge 50 Ultra if you photograph or shoot video regularly and want the better imaging pipeline of the two. The biggest gaps in its favor are front camera, wired charging, weight, among others.
Pick the MIX Fold 4 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 antutu, screen size, battery capacity, among others.
Both ship with comparable ram, main camera, 5g support, so those specs do not 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 says both are well-rounded; the differences are about trade-offs, not quality.
