Which should you buy?
The Z70 Ultra is the clear pick on raw spec strength, leading by 11.9 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 Z70 Ultra if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are wired charging, antutu, ram, among others.
Pick the Pixel 9a if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are weight, pixel density, promised os updates.
Both ship with comparable 5g support, water resistance, 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.
