  2. How important is maximum performance and a high refresh rate display?
  3. What is your budget and storage requirement?

Scenario-Based Recommendations:

  • Gamer: ROG Phone 8 Pro for its higher refresh rate, superior performance due to larger RAM, and gaming-centric features (though not listed here, ROG phones typically have gaming-specific features).
  • General User: Zenfone 11 Ultra offers a balanced experience at a potentially lower price point.
  • Power User/Content Creator: ROG Phone 8 Pro for its superior performance and large RAM & Storage.

My Choice: Asus ROG Phone 8 Pro

While both phones offer impressive specifications, the Asus ROG Phone 8 Pro edges out the Zenfone 11 Ultra due to its larger RAM and storage configuration, potentially smoother display (165Hz), richer color depth (1B colors) and more versatile USB options. The extra RAM is crucial for demanding tasks and future-proofing the device. The DisplayPort and OTG support enhance productivity and connectivity. Although the Zenfone 11 Ultra offers more color choices, the performance and productivity benefits of the ROG Phone 8 Pro outweigh the aesthetic preference for me. I prioritize functionality and future-proofing over purely aesthetic considerations.
