  2. What do you use your smartphone for primarily? Consider if you prioritize gaming, photography, or simply basic tasks.

My Choice

If I were choosing between these two phones, I would unequivocally select the Oppo Find X3 Pro. While the Oppo A55 has a larger battery and a side-mounted fingerprint sensor, the Find X3 Pro simply offers a far superior user experience across the board in almost all areas. The significantly better display (AMOLED, higher resolution, and 120Hz refresh rate), combined with the massively faster Snapdragon 888 processor, higher quality camera with much more advanced features, stereo speakers, fast charging, and all the other advanced features justify its higher price. Even if I was not a heavy user, the sheer improvement in overall experience in day-to-day tasks is something that I would appreciate, and would definitely make the phone more useful and enjoyable.
