Which should you buy?
The Z70 Ultra is the clear pick on raw spec strength, leading by 13.4 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 iPhone 17 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 wireless charging, weight, pixel density, among others.
Pick the Z70 Ultra 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 wired charging, ram, battery capacity, among others.
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.
