Which should you buy?
The OnePlus 12 edges ahead on the Mars Score (64.6 vs 69.6), but the 5.0-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Galaxy S26 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 weight, antutu, water resistance, among others.
Pick the OnePlus 12 if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are wireless charging, front camera, wired charging, among others.
Both ship with comparable ram, main camera, refresh rate, so those specs don't separate the two — focus on the differences below.
Bottom line: the OnePlus 12 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
