My Choice:
If I were choosing between these two phones, I would personally opt for the OnePlus 9. While the Poco X3 GT is undoubtedly a strong contender in the mid-range category, the superior AMOLED display with higher brightness, the added horsepower of the Snapdragon 888, and its more versatile camera system align better with my personal usage needs. Specifically, the high-quality display and the wireless charging capabilities would be more convenient, even if it means a trade-off with battery life. Though the Poco offers a larger battery and faster charging, the benefits of having more advanced camera features and a better quality display, and software support of the OnePlus 9, outweighs the compromises.
