My Choice
If I were choosing, I would pick the Oppo Find X3 Pro. Here's why:
- Superior Overall Experience: While the Samsung Galaxy A02s is a good basic option, the Oppo Find X3 Pro offers a significantly better experience in almost every aspect. The vastly superior display, performance, camera capabilities, and charging speeds provide a much more enjoyable and versatile device.
- Future-Proofing: With the Snapdragon 888, 12/16 GB of RAM, and more advanced features, the Oppo is far more future-proof, meaning it will remain usable and relevant for longer compared to the lower powered A02s.
- Photography and Videography: My use case often involves taking photos and videos, so the Oppo's significantly improved camera system is a huge benefit.
- Value for Money (in the long term): While the Oppo is more expensive, the increase in functionality, speed, and overall experience will save a significant amount of time and frustration. If I were to choose the A02s, I would quickly find myself wanting to upgrade, costing more money in the long term.
Although the battery life of the A02s is better, I can make do with the slightly smaller battery of the X3 Pro, given that the fast charging and wireless charging features are incredibly useful. Ultimately, I would rather have a phone that is better and more enjoyable to use in almost every regard than one that has a slightly larger battery. The improvements in screen, performance, camera and connectivity are worthwhile, and a better experience is worth paying for.
