Which should you buy?
These two are nearly even on the Mars Score (62.5 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) 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 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, ram, antutu, among others.
Both ship with comparable main camera, refresh rate, 5g support, 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.
