My Choice and Why

If I had to choose between these two phones, I would pick the Xiaomi Poco X3 Pro.

My Reasoning:

As someone who appreciates smooth performance and often engages in mobile gaming and multimedia, the significantly more powerful Snapdragon 860 chipset, coupled with the Adreno 640 GPU and stereo speakers, makes the Poco X3 Pro the better pick. The fact that it offers 4K recording capabilities also makes it a better option for higher quality videos. The slightly less modern design and older OS version are a fair trade-off for the much-improved performance in my opinion. The added screen protection gives me a bit more peace of mind too.

While the Realme 9 Pro has its advantages, such as a lighter build and potentially better low-light selfies, they don't outweigh the performance and multimedia benefits offered by the Poco X3 Pro for my usage patterns. The inclusion of a compass and ultrasonic proximity sensor also makes it a more complete package for me.
