Pick the Phone (3a) Pro 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.
Pick the OnePlus 14 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are antutu, wired charging, ram, among others.
