My Choice and Why

If I were choosing between these two, I would choose the Google Pixel 8a, even if it comes at a premium price.

Here’s my rationale:

  • Future-Proof Performance: The Tensor G3 chip in the Pixel 8a is a major win for me. It’s not just about raw power; the AI capabilities and overall snappiness will keep the phone feeling fast and responsive for years to come. The Moto's chipset, on the other hand, already feels outdated by comparison.
  • Camera Supremacy: As someone who loves photography, the Pixel’s camera system is the obvious choice. The combination of high-quality sensors and Google’s advanced image processing is unmatched in this price range. Features like OIS and 4K video are crucial for capturing memorable moments.
  • Premium Display: The difference between an LCD and an OLED is something that I notice, and with the higher pixel density and vivid colors, the Pixel 8a's display is better.
  • Software and Support: The Pixel's advantage with the latest Android version and updates is significant. I value getting the newest features and security updates as soon as they are available. I also appreciate the cleaner software experience with no bloatware.
  • Smaller Package: The smaller size of the Pixel makes it more comfortable for everyday use.

While the Moto G51 5G has its strengths, particularly for budget-conscious users or those who value a large screen, the Pixel 8a's combination of performance, camera, software, and build quality makes it a clear winner for my needs.
