What I Would Choose

Given the information provided, I would choose the realme 8, if the data for this phone were not missing.

Here’s why:

  • Display Quality: As a tech journalist, I deeply appreciate a great display, and the AMOLED screen with a 120Hz refresh rate in realme 8 would dramatically enhance the overall experience.
