OnePlus Open 2 vs Xiaomi 15 Pro

These two are nearly even on the Mars Score (74.5 vs 74). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the OnePlus Open 2 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 screen size.

Pick the Xiaomi 15 Pro 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 pixel density, weight, wired charging, among others.

Both ship with comparable ram, main camera, refresh rate, 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.
