Which should you buy?

Pick the Galaxy S26+ 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, antutu, among others.
Pick the OnePlus 13R 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 wired charging, front camera, battery capacity, among others.

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.
