My Choice

If I were to choose between these two phones, I would pick the Xiaomi Poco X6.

Here's why:

While the Realme GT 5G offers a significant advantage in raw performance, the Poco X6 presents a more well-rounded experience for my typical usage. As a user that prioritizes general use over high-end gaming, the Poco X6's brighter display, larger battery, more modern software and video stabilization, all come together for a better overall experience for my needs. I also value the longer software support and slightly more modern design of the Poco X6. While I would miss the added performance of the Snapdragon 888, the tradeoff of better battery life, a brighter screen, and newer features is worth it for my requirements. I also value the better screen protection.
