Which should you buy?
The Reno 13 Pro edges ahead on the Mars Score (62.5 vs 68.3), but the 5.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The Phone (3a) doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
Pick the Reno 13 Pro if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are antutu, wired charging, front camera, 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: the Reno 13 Pro is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
