Which should you buy?
The OnePlus 15 edges ahead on the Mars Score (78.4 vs 74), but the 4.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the OnePlus 15 if you photograph or shoot video regularly and want the better imaging pipeline of the two. The biggest gaps in its favor are front camera, antutu, ram, among others.
Pick the GT Neo 7 if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight.
Both ship with comparable main camera, screen size, refresh rate, so those specs don't separate the two — focus on the differences below.
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.
