My Choice

If I had to choose between these two phones, I would pick the Realme 8. Here's why:

  • Superior Display: The significantly higher resolution and brightness of the Realme 8 make it much more enjoyable for daily use, especially for browsing, watching videos, and gaming.
  • Faster Charging: The 30W fast charging is a huge convenience, ensuring I can quickly top up the phone before heading out.
  • Balanced Performance: While both have similar benchmarks, the practical combination of a better display and faster charging is something I prioritize.
  • Better Standard Camera: The standard camera resolution is better than the Samsung A42 5G and is something I prioritize over the selfie camera since I don't use it as much.
  • Hi-Res Audio: As someone who likes listening to music, Hi-Res audio is a big plus.

While the Samsung Galaxy A42 5G has a larger display, the lower resolution and brightness are significant drawbacks for me. The Realme 8 offers a more well-rounded package with its focus on display quality, charging speed, and main camera performance. The differences in other features between the two devices such as the software and additional sensors are not enough to sway my decision between the two devices.
