Between the Razr 50 and Z70 Ultra, the Razr 50 comes out ahead in front camera / weight, while the Z70 Ultra wins on antutu / wired charging. Overall, the Razr 50 scores 60.2 and the Z70 Ultra scores 75.1 on our Mars Score.
Which should you buy?
The Z70 Ultra is the clear pick on raw spec strength, leading by 14.9 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 Razr 50 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, weight, pixel density, among others.
Pick the Z70 Ultra 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, wired charging, ram, among others.
Both ship with comparable main camera, 5g support, optical image stabilization, so those specs do not separate the two — focus on the differences below.
Bottom line: the Z70 Ultra is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
