My Choice and Why

If I were choosing between these two, I would go with the Xiaomi 12X. As someone who appreciates top-tier performance, a great display, and high-quality photography, the 12X is the obvious choice. The difference in screen quality alone is enough for me to pick the 12X.

I need the screen to be sharp, bright and vibrant, and I need the phone to keep up without any stuttering. While the Poco M4 5G has a larger battery, the 12X will still get me through the day, and its much faster charging will make sure I am never too long out of juice. I understand that the 12X is more expensive, but for my personal usage, the superior experience is worth the extra investment. It's about optimizing the features that matter most to me, and for me, that is premium performance, a crisp display, and versatile photography capabilities.
