My Choice and Why:

If I were to choose between these two phones, I would personally go for the Xiaomi 12X. Here's my reasoning:

  • Performance: The Snapdragon 870 offers a noticeable performance edge in benchmarks and in real world usage, which is important for my use case which is mobile gaming and demanding applications.
  • Display: The 120Hz refresh rate makes a huge difference in daily usage, making the phone feel much smoother and responsive and I highly value the user experience and the responsiveness it offers.
  • Future Proofing: The use of Gorilla Glass Victus makes the phone more resistant to scratches and cracks, offering better long-term durability which is a priority for me.
  • 8K Video: While I don't shoot in 8K frequently, having the option is beneficial and I value the possibility of using it for professional content creation.
  • Slightly More Compact: I do prefer the smaller size of the Xiaomi 12X as it is easier to use single-handedly and carry around.

While the Oppo Find X3 Neo has a more versatile camera system, my personal use case prioritizes performance and a smoother display experience. The trade-offs of a slightly less impressive camera system are acceptable for me as it allows for better gaming, smooth animations and the long term durability benefits.
