What I Would Choose and Why

If I were choosing between these two phones, I would personally choose the Asus Zenfone 8. My decision is primarily based on the significantly superior display quality (AMOLED, high resolution, high refresh rate, high brightness), the flagship-level performance of the Snapdragon 888 chipset, and the advanced camera capabilities.

I value a great viewing experience when consuming media, and the Zenfone 8's screen is far superior for this. I also value a smooth and responsive user experience, and the performance difference between the Snapdragon 888 and the Helio G85 is very large. Although the Zenfone 8 is an older device and has a smaller battery, the overall premium experience it offers is worth the trade-off for me. While the Poco C65 has a larger screen and longer battery life, the trade-off in display, performance, and camera quality is too great for my preferences.

In summary, for me, the Zenfone 8 provides a better overall experience due to its premium components, and the features I would use most frequently are the ones in which it excels.
