Which should you buy?
The Razr 50 Ultra edges ahead on the Mars Score (65.6 vs 62.5), but the 3.1-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Razr 50 Ultra 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, ram, refresh rate, among others.
Pick the Phone (3a) if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are battery capacity, wired charging.
Both ship with comparable main camera, 5g support, front camera, so those specs do not 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 says both are well-rounded; the differences are about trade-offs, not quality.
