My Choice
If I were choosing between these two phones, I would pick the Realme GT2 Pro. While the OnePlus 9 does have some compelling features like wireless charging and a better main camera sensor, the superior display clarity, brighter screen, faster performance, longer battery life, and the inclusion of OIS on the Realme GT2 Pro make it a more well-rounded and future-proof device. The difference in display sharpness alone is a significant factor for daily use. Though the lack of an AMOLED display is a slight downside for the Realme GT2 Pro, the overall package it offers makes it the better pick for me. The superior chipset and GPU make it a better fit for long-term usage and demanding tasks, and I value the slightly better battery life offered.
