  • Scenario 3: Travel and Photography Focus: If eSIM support is crucial for your travel needs and you value the ToF sensor for portrait photography, the Note20 5G might be a better fit, but consider the significant performance and software drawbacks.

My Choice

If I were choosing between these two phones, I would pick the Asus Zenfone 11 Ultra. While the Samsung Galaxy Note20 5G has a more compact and lighter design, the performance difference and improved modern features of the Zenfone 11 Ultra are just too good to pass up. The Snapdragon 8 Gen 3, 144Hz display, larger battery, and significantly better software support make it a far more future-proof device. The camera, while not perfect, is also a significant upgrade. While I appreciate the barometer on the Note20, I can live without it. The improved longevity and user experience offered by the Zenfone 11 Ultra outweigh the Note20's benefits for my daily use.
