My Choice and Why

If I had to pick one, it would be the Xiaomi 13, hands down. As a tech journalist and analyst, I value cutting-edge performance, a superior camera experience, a good display, and fast charging, all of which the Xiaomi 13 delivers in spades. While the G51 has a larger screen and a lower price point, the performance difference is significant enough to warrant spending more on the Xiaomi 13 for its improved user experience and better image quality. For me, the difference in overall quality and the future-proofing aspects make it the more sensible choice. It's a device that's built to be used and enjoyed every single day without compromise, and to be honest, I'd rather spend more to get a phone that's powerful and has a great camera that I can use to take quality photos rather than a big screen on an underpowered device that I will struggle to use.
