My Choice
I would choose the OnePlus 9 Pro. While the Samsung Galaxy A23 5G is a decent budget phone with great battery life, the OnePlus 9 Pro offers a significantly superior overall experience, especially in areas that matter to me most: display quality, performance, and camera capabilities.
- Display: The higher resolution and brightness make the viewing experience more enjoyable, especially for media consumption and gaming.
- Performance: The Snapdragon 888 ensures a smooth and responsive user experience, vital for multitasking and running demanding applications.
- Camera: As someone who enjoys taking photos and videos, the versatile camera setup, better image quality, and 8K video capability are major advantages.
- Fast Charging: The 65W fast charging and wireless charging are highly convenient.
While the A23 5G offers a larger battery, the 9 Pro's much faster charging negates much of the battery difference for me, as it can quickly charge up in a very short time. I'm happy to trade off some battery life for the better quality in other areas. The price difference is justified for the level of performance upgrade in the 9 Pro.
