My Choice
Personally, I would choose the Samsung Galaxy S24 Ultra. Here’s why:
While I appreciate the Xiaomi 12's compact design and faster charging, my needs prioritize performance and a top-tier camera. As someone who often pushes devices to their limits for testing and content creation, the Snapdragon 8 Gen 3 processor in the S24 Ultra, combined with its exceptional camera system, makes it a far more versatile tool for my needs. I'm willing to tolerate the size and slower charging speeds because the trade-off is worth it for my use case. The high resolution display, the significantly better brightness, more storage, and the latest version of Android also make it a more compelling choice for me. Plus, the versatility of the camera system and its ability to take stunning pictures in varied conditions is a significant draw.
Ultimately, the best choice depends on your specific priorities. Both are excellent phones, but they cater to different types of users. The S24 Ultra wins on sheer power and camera prowess, but the Xiaomi 12 is no slouch and offers a great value for those who prefer a compact form factor.
