My Choice
I would choose the OnePlus 9.
While the Samsung Galaxy A53 5G has its merits, my personal preference leans towards a smoother, faster overall experience. The vastly superior performance of the Snapdragon 888, the brighter display, and the significantly faster charging are features I prioritize. I am not concerned about the trade-offs of having less battery life or missing a dedicated macro lens, as the core performance and display capabilities of the OnePlus 9 better align with how I would use the phone. I'm also interested in the flexibility of professional camera features like manual mode and 8k recording. While having a newer software OS is nice, I find it less critical than the performance gains offered by the OnePlus 9.
