My Choice

Based on the analysis, I would choose the Xiaomi Poco X3 Pro.

The trade-offs of a slightly heavier design and missing reverse charging are negligible compared to the significant performance advantages the X3 Pro provides. As an analyst, I understand the value the M3 Pro 5G offers at a lower price point but the performance and display trade-offs are too much to ignore if I was in the market for a new phone.
