Which should you buy?
These two are nearly even on the Mars Score (63.8 vs 65.2). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
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, screen size.
Pick the 13 Pro+ 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 wired charging, antutu, weight, 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: 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.
