  3. What's your budget? Premium price for Apple ecosystem or value for performance?

My Choice: Asus Zenfone 11 Ultra

While the iPhone 15 Pro offers a premium, compact design and a polished user experience, the Zenfone 11 Ultra wins out for me due to its compelling combination of performance, battery life, and value. The larger display and higher refresh rate are also significant advantages for my media consumption and gaming habits. While I acknowledge the subjective preference for iOS, the Zenfone 11 Ultra's objective advantages in key areas make it the more appealing choice. The significantly larger battery, doubled RAM, and lower price point outweigh the benefits of the iPhone for my personal needs. The slightly smaller, sharper display of the iPhone wouldn't offset the Zenfone's advantages in daily use for me.
