My Choice
I would choose the Xiaomi Redmi Note 9T. While it's an older model, it offers a vastly superior experience in terms of performance, display quality, camera capabilities, and charging speed. The Redmi A2 sacrifices too much performance for a marginal increase in software version. The Note 9T is the clear winner in terms of value and overall capabilities and it offers better build quality with Gorilla Glass protection. While the Redmi A2 is lighter and has a more recent version of Android, these benefits are overshadowed by its significant performance limitations.
