Final Recommendation

I would choose the Oppo Find X3 Pro.

Here's why:

While both phones have their use cases, the Oppo Find X3 Pro provides a significantly better experience across the board. The display is noticeably superior, offering much more vibrancy, clarity, and brightness, which is important for daily use and media consumption. The significantly faster processor and GPU and much larger RAM, and makes it a far more future-proof device. The camera system is also substantially better, offering much higher quality photos and videos with more versatility through telephoto and wide angle options as well as advanced camera modes like RAW. The 65w fast charging also means minimal downtime and the larger battery ensures a full day of use and more. While its launch date is a bit older (2021), the raw capabilities of the device far surpass anything that the Oppo A77 offers.

While the A77 is more budget-friendly, for me, the difference in daily user experience is significant enough to justify the additional cost of the X3 Pro. The A77 is a great budget option, but only if your budget is your priority.

My preference for the X3 Pro is driven by the following:

  • Uncompromising Performance: I prioritize a smooth, responsive user experience in apps, gaming, and content creation, and the X3 Pro has a clear advantage in performance.
  • Superior Visual Experience: The difference in display quality is significant, providing a far more immersive and enjoyable experience for media and general use.
  • Versatile Camera System: I appreciate a capable camera that can handle various situations with high quality output, giving me the flexibility to capture any moment with exceptional clarity and detail.
  • Future Proofing: While it was released in 2021, the X3 Pro remains a capable phone with premium hardware that will allow for a smoother and longer experience compared to the budget focused A77.

For anyone who appreciates a better experience, the X3 Pro is undoubtedly the better option.
