Which should you buy?
The OnePlus 15 edges ahead on the Mars Score (73.8 vs 78.4), but the 4.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the OnePlus 14 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 pixel density, weight.
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. Its strongest claims are battery capacity, wired charging, antutu, among others.
