Which should you buy?
The OnePlus 15 edges ahead on the Mars Score (78.4 vs 71.7), but the 6.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the OnePlus 15 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 wireless charging, ram, wired charging, among others.
Pick the X200 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.
Both ship with comparable main camera, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
Bottom line: the OnePlus 15 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
