Which should you buy?
The Z70 Ultra is the clear pick on raw spec strength, leading by 12.6 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 photograph or shoot video regularly and want the better imaging pipeline of the two. The biggest gaps in its favor are front camera, weight.
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, ram, wired charging, among others.
Both ship with comparable main camera, 5g support, optical image stabilization, so those specs don't 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.
