My Choice
I would choose the Xiaomi Poco X3 NFC. While the larger battery of the C40 is appealing, the massive performance difference, vastly superior display, and significantly better camera system of the X3 NFC are too significant to ignore. The 33W fast charging mitigates the battery capacity difference to some extent. I would also rather have the screen protection of Gorilla Glass 5 versus Gorilla Glass 3. Given my use case, I value performance and media consumption quality much more than a slightly longer battery life.
