If I were choosing between these two phones, I would choose the Oppo Find X3 Pro. While the Xiaomi Poco M3 Pro 5G is a solid budget option with good battery life, the Oppo Find X3 Pro offers a significantly superior experience in almost every other aspect.

Here's why:

  1. Display Quality: The AMOLED display with higher resolution, refresh rate, and brightness on the Oppo is a game-changer for me. I often watch videos, browse social media, and play games on my phone, so the significantly better display would make a big difference to my experience.

  5. Build Quality: The Oppo Find X3 Pro's Gorilla Glass 5 is a nice touch for longevity, offering better screen protection.

While the Xiaomi Poco M3 Pro 5G has a larger battery, the other advantages of the Oppo Find X3 Pro make it the preferable choice for me. I prioritize display quality, performance, and camera quality over raw battery capacity. The extra cost is justified by the significant improvements in user experience for my needs.
