My Choice
If I were choosing between the two, I would lean towards the Samsung Galaxy M12. While the Oppo A54s has some appealing features like reverse charging and a lighter design, the smoother 90Hz display, faster charging, and more versatile camera system of the M12 is more useful for my typical use case. The slightly better performance in benchmarks also indicates a snappier general experience. I value the additional Wide Angle lens and dedicated depth sensor. Additionally, the extra option of 6GB of RAM provides more headroom for multitasking. The slightly heavier design is an acceptable trade-off for the overall better daily performance and features the M12 offers.
