Which should you buy?
These two are nearly even on the Mars Score (68.7 vs 69.6). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the Phone (3) if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, water resistance, promised os updates.
Pick the OnePlus 12 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, wired charging, pixel density, among others.
