My Choice

I would choose the Xiaomi Redmi Note 10. While the Nokia G21 offers a slightly smoother 90Hz refresh rate, the overall experience offered by the Redmi Note 10 is significantly superior. The AMOLED display with its high resolution and brightness alone makes the Redmi Note 10 a winner for me, given how often I consume media. The better chipset, camera system and faster charging are also important advantages. While I appreciate the slightly smoother refresh rate on the Nokia G21, the trade-offs in display quality, performance, and camera versatility are too significant for my usage habits. The Redmi Note 10's display, faster charging and cameras align better with my needs, making it the more compelling choice.
