My Choice
If I were choosing between these two phones, I would choose the vivo V40. While the Xiaomi Redmi Note 9T has a few advantages like the stereo speakers and the inclusion of a charger, the sheer technological advantages of the vivo V40 make it a significantly better choice for most users. The vastly superior screen, the much more powerful processor and GPU, the better camera, the much faster charging and the up-to-date Android OS make the vivo V40 worth the added cost. The Redmi Note 9T is an aging smartphone and using old technology. Therefore, despite some nice audio features, it cannot compete with the vivo V40.
