My Choice

If I were choosing between these two phones, I would pick the OnePlus 9. Here's why:

  • Performance is king: As a tech enthusiast who uses my phone for a variety of tasks, including gaming, heavy browsing, and content creation, the Snapdragon 888 chipset and 12GB of RAM in the OnePlus 9 offer a significantly smoother and more responsive experience. The benchmark scores clearly highlight the performance gap between the two phones, making the OnePlus 9 the obvious choice for demanding usage.
  • Superior display: The AMOLED screen is a game-changer, especially when watching videos or consuming content outdoors in sunlight. The high brightness and vibrant colors are a huge plus. While the Motorola Moto G55 may have the same resolution, the IPS LCD just doesn't measure up to the richness of an AMOLED display.
  • Camera versatility: The camera on the OnePlus 9 is simply better with its additional lenses and video recording capabilities. As a user who enjoys taking high quality photos and videos, the flexibility and quality offered by the OnePlus 9 are essential.
  • Faster Charging: The OnePlus 9 charges much faster, which is a crucial convenience factor when time is of the essence.
  • Although the Moto G55 has a larger battery, the vastly superior performance and better display of the OnePlus 9 make it a worthy tradeoff. In my experience, the 4500mAh battery of the OnePlus 9 is generally sufficient for a full day of usage with typical usage patterns. If needed, I value the faster charging speed over a marginal increase in battery capacity.

While the Motorola Moto G55 has its strengths, such as the larger battery, eSIM, and reverse charging, the OnePlus 9's advantages in performance, display, and camera are more important for my usage style and preferences.
