  • If you're an avid photographer and want advanced camera features such as optical zoom, the Oppo Find X3 Pro is the only viable choice here as the M55 lacks optical zoom.
  • If you’re a tech enthusiast who want the latest tech the Oppo Find X3 Pro is the better option with wireless charging and a higher quality chipset, but the M55 has the newest OS.

My Choice

If I were choosing, I would opt for the Oppo Find X3 Pro. Despite its older software (which is upgradeable to Android 14), the superior display quality, significantly better performance, the more versatile camera system, and faster charging capabilities are major advantages that are more important to my personal use cases. I would rather compromise on a slightly older OS than on the performance and camera aspects, especially since both phones are not offering expandable storage. The higher resolution display and superior brightness make it better suited for my needs. The wireless charging and reverse wireless charging would be an additional nice-to-have feature, and are not present on the M55. While the M55 has a larger battery, the 65W charging on the Find X3 Pro makes up for it, providing me with convenience.
