My Choice
If I had to choose between these two devices, I would pick the OnePlus 9. My primary use case involves gaming, media consumption (especially high-resolution videos), and photography/videography. The OnePlus 9 offers a much better screen with its AMOLED panel, and the performance is in a completely different league, allowing for a smoother and more enjoyable experience. While the Realme C61 does have a larger battery and a newer version of Android, the core experience provided by the OnePlus 9 is superior for my needs and justifies the extra cost.
The OnePlus 9's superior camera setup, along with the wireless charging capability, are also significant bonuses that make it a well-rounded device for my usage. Although the OS is older, I would prioritize the overall better hardware experience over a newer version of Android. The main strength of the C61 is a lower price and the newest Android version which are things I value, but are not as crucial to me as overall performance, camera quality, and display.
