My Choice

If I were to choose, I'd definitely go with the Xiaomi 12 Pro. While both phones have their place, the 12 Pro's superior display, flagship performance, and a much better camera system are worth the extra money. I appreciate a phone that can handle anything I throw at it and provides an excellent multimedia experience. Plus, the faster charging speeds are a real bonus for my on-the-go lifestyle. The Realme 9i is okay, but the trade-offs in screen, speed, and camera are just too large to ignore, for me at least.
