Which should you buy?
The Zenfone 11 Ultra edges ahead on the Mars Score (71.9 vs 67.5), but the 4.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Zenfone 11 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, ram, among others.
Pick the iPhone 17 Pro Max 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 wireless charging, pixel density, screen size, 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: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
