My Choice

I would choose the Xiaomi Redmi Note 10 Pro.

Explanation:

While the Realme 9i may have a slight edge in price, the Redmi Note 10 Pro offers a significantly superior user experience in almost every other aspect that matters for me:

• Display: The AMOLED display with a 120Hz refresh rate is a major advantage. It offers a much more enjoyable viewing experience for media consumption, gaming, and everyday use.
• Performance: The Snapdragon 732G is a much more powerful chipset, leading to faster app loading, smoother multitasking, and a better gaming experience. The AnTuTu score alone demonstrates this performance gap.
• Camera: The 108MP main camera, coupled with additional lenses (wide-angle, portrait) and 4K recording capabilities, offers much greater versatility and image quality compared to the Realme 9i.
• Audio: The inclusion of Dolby Atmos offers a better audio experience.
• Sensors: The additional gyroscope and ultrasonic proximity sensor are very good for gaming.
• Build Quality: The superior screen protection on the Xiaomi is a massive benefit

For me, the improvement in display quality, performance, camera versatility, and audio outweighs the benefits of a slightly newer phone and potentially slightly better battery life with the Realme 9i. The Redmi Note 10 Pro provides a more premium experience and offers much better value in the long run if its price is not drastically more expensive. I am willing to pay a bit extra for these improvements. If the phones are the same price, the Redmi Note 10 Pro becomes an obvious pick.
