Final Thoughts

Both the Motorola Moto G51 5G and the Realme 9 are capable devices with their own strengths. The Moto G51 is a performance focused device with a 120Hz screen which is great for gaming or smooth scrolling. The Realme 9 offers superior display technology, faster charging, and a higher-resolution camera but sacrifices processing power and is limited to 4G.

If I had to choose, I'd lean towards the Realme 9. While the Moto G51 has a performance edge and a smoother display, I value the Realme 9's superior AMOLED screen and its high-resolution camera a bit more for daily usage. The faster charging is also a huge plus for my busy schedule. The only major caveat is the lack of 5G, if this is important to you, the Moto G51 is a better fit. The fact that the Realme 9 is lighter and more compact makes it a more convenient device to carry around, and overall, the screen, camera and charging speed make the Realme 9 more suitable for my daily needs.
