My Choice: Asus Zenfone 11 Ultra
While the iPhone 15 offers a polished and compact design, the Zenfone 11 Ultra's combination of a large, high refresh rate display, significantly larger battery, powerful performance with 16GB RAM, and advanced camera features makes it a more compelling device for my needs. I prioritize a large screen for productivity and media consumption, long battery life for all-day use, and the flexibility of the Android ecosystem. The slightly larger size and weight are trade-offs I'm willing to make for these advantages. The 144Hz refresh rate and the extra RAM for future-proofing are also deciding factors. While I acknowledge the iPhone's strengths in portability and its historically strong video quality, the Zenfone's overall package better suits my usage patterns and preferences.
