Which should you buy?
The Phone (3) edges ahead on the Mars Score (68.7 vs 63.8), but the 4.9-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Phone (3) 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 antutu, wired charging, pixel density, among others.
Pick the Phone (3a) Pro if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are front camera, screen size.
Both ship with comparable ram, main camera, refresh rate, so those specs don't separate the two — focus on the differences below.
