Which should you buy?
The OnePlus 15 edges ahead on the Mars Score (78.4 vs 74), but the 4.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the OnePlus 15 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are wireless charging, wired charging, battery capacity, among others.
Pick the X200 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.
Both ship with comparable ram, main camera, screen size, 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.
