What I Would Choose and Why

If I were choosing between these two phones, I would choose the Oppo A54 5G. The primary reason is its significantly superior performance, which directly translates to a smoother and more enjoyable user experience. The Snapdragon 480 5G chip outperforms the Helio P35 by a significant margin, making everything from app loading to multitasking faster and more fluid.

Additionally, the Oppo A54 5G's superior display with higher resolution and refresh rate contributes to a much better viewing experience. The camera system on the Oppo is better on nearly all fronts. While it lacks a telephoto and depth sensor on the A12, the quality is higher in the other lenses, and it has additional macro and black/white lenses which the A12 lacks. The faster charging, more RAM and storage options, and advanced connectivity make it the better overall package for a small increase in price.

The small price difference is easily justified by the vastly superior performance, better display, better camera, and overall experience. The Samsung Galaxy A12 simply cannot compete in terms of providing a modern smartphone experience. While the A12 may be acceptable for the most basic of users, I would still recommend the Oppo A54 5G for nearly all use cases.
