While potentially slightly more expensive, the superior performance, stunning AMOLED display, and vastly improved camera system make it a far more compelling device. The smoother 90Hz refresh rate and significantly brighter screen are tangible improvements that elevate daily use. For me, the long-term benefits of a smoother, faster, and more visually appealing experience outweigh any potential cost savings. The Realme 9 feels like a future-proof investment, capable of handling demanding tasks and providing an enjoyable user experience for years to come.
