My Choice

Personally, I would choose the Xiaomi Poco X6. While the Zenfone 8 has an undeniably more powerful processor and a more robust camera on paper, the practical benefits of the Poco X6 align more closely with my daily usage. As a user who consumes a lot of media, the larger, brighter screen is a significant advantage, and I value the much better battery life that the Poco X6 offers. The significantly faster charging is also a huge win for convenience. While I would enjoy the Zenfone's camera capabilities and higher power, the day-to-day benefits of the Poco X6 are more compelling for my specific use case.

I will note that if I was someone who did a lot of gaming or video editing on my phone, I would choose the Zenfone 8 without hesitation, but those are not my use cases.
