What I Would Choose and Why

If I were choosing between these two, I would absolutely go with the Samsung Galaxy A55. Here's why:

As a tech journalist and analyst, I need a phone that can keep up with a wide array of tasks. The Galaxy A55 is the clear winner in almost every category that matters:

  • Performance: I regularly run benchmark tests and multitask with numerous apps, and the Exynos 1480 processor is much more capable than the Helio G35. This also improves the longevity of the device as it'll be able to run more intensive applications down the line.
  • Display Quality: I value a sharp, vibrant screen for reviewing photos and videos, and the AMOLED display with 120Hz is a game changer for smooth scrolling and immersive media.
  • Camera Versatility: I'm often capturing images and videos for reviews, so the A55's higher resolution sensors, ultrawide lens, 4K recording, and image stabilization are essential.
  • Future-Proofing: I like to use devices for the long run, and the A55 has newer connectivity options, a more modern OS, and a more durable design. These features ensure it'll still be relevant a couple of years down the line.
  • Overall Experience: It simply offers a more polished and premium user experience, from the enhanced audio to the more versatile software features.

While the Oppo A57 4G has its place for the tightest of budgets and people that want the basics, the Samsung Galaxy A55 offers significantly more bang for the buck. It's a more capable, versatile, and future-proof smartphone. I would gladly trade off the A57's slightly faster charging for all the advantages that the A55 brings to the table. In my opinion, the A55 isn't just better, it's a completely different experience.
