  3. How important are display quality, performance, and camera features to you?

What I Would Choose and Why

Given my analysis and personal preferences, I would choose the Oppo Find X3 Neo. Here's why:

  1. Superior Overall Experience: The Oppo Find X3 Neo offers a dramatically better user experience across key aspects:

    • Display: The AMOLED display with its high resolution and brightness is crucial for my daily usage, which involves a lot of media consumption and working outdoors.
    • Performance: The Snapdragon 865 chipset provides much smoother performance, which is essential for multitasking and the occasional mobile gaming I enjoy.
    • Camera: As someone who takes photos frequently, the versatile and high-quality camera system of the Oppo Find X3 Neo, with features like optical zoom and image stabilization, is a big advantage.
  2. Long-Term Value: While the Xiaomi Redmi A3 is more recent and has a bigger battery, it is an older device with the most recent software updates (android 12), its drawbacks in display, camera and performance would make it an inferior option long term. The Oppo Find X3 Neo has more powerful hardware, even though its a older device and therefore more likely to offer a more pleasant and more reliable experience for the next few years.

  3. Ignoring Budget Constraints: While the price may be a factor for many users, if I were to prioritize functionality, the Oppo Find X3 Neo would be my choice.

In summary, the Oppo Find X3 Neo’s strengths in display, performance, and camera capabilities far outweigh the benefits of the Redmi A3's newer OS and slightly longer battery life, especially given my use case where I want a more enjoyable, more reliable smartphone experience.
