My Choice:
If I were to choose between these two phones, I would pick the vivo X100. Here's why:
- Performance Matters: The vivo X100's newer chipset and higher AnTuTu scores indicate a significant performance difference. This translates to a smoother user experience, faster app loading, and better gaming capabilities. As someone who uses their phone for demanding tasks, this is crucial.
- Superior Camera System: The vivo X100's main, selfie, and telephoto cameras, along with the additional software features (Cinematic Mode, OIS, Gimbal, Laser AF) offer a far more versatile and higher quality photography experience than the OnePlus 9.
- Excellent Display: The substantially higher brightness (3000 nits vs 1100 nits) on the vivo X100 is a game-changer for outdoor visibility, making it perfect for use in any environment.
- Future-Proofing: The newer OS (Android 14) and support for the latest Wi-Fi and Bluetooth standards give the vivo X100 a longer lifespan and ensures I get the most out of new technologies.

Given the significant improvements in these crucial areas, the vivo X100 is the better choice for my needs. The trade-off for a slightly bulkier phone is well worth the improvements in every other aspect.
